A 3-Way construction is available, which is perfectly suited for accurate temperature control.The engineered passages within the GX valve body provide optimal capacity and create a stable flow pattern for smooth operation in every valve size.Actuator sizing and selection is determinedautomatically by the valve body configuration. No extra engineering is required.The GX actuator controls up to a 51.7 bar (750 psig) pressure drop. Its multi-spring design is field-reversible from spring-open to spring-close action.A carefully selected lineup of valve body and trim materials means you can apply the GX to a wide range of service situations. Carbon and stainlesssteels are GX standards along with a choice of several alloys for more corrosive applications.Metal-to-metal seating is standard, with options including PTFE soft seating for Class VI shutoff and hardened trim with a Stellite overlay for erosive applications.You can use the GX for either throttling or on-off control, with or without a positioner. Digital and analog positioners can be specified, as well as auxiliary solenoids, limit switches and otheraccessories. The GX is compatible with the NAMUR (IEC 60534-6-1) mounting standard.Emerson engineers started with a clean slate in developing Fisher ® GX control valves. Theirgoal was to bring unmatched innovation, technology and reliability to control valve ownership. GX control valves are the result. They provide reliable operation over a wide range of applications and come in a variety of sizes and materials.Designed to meet your needs, digital GX control valves with integrated FIELDVUE ™ DVC2000 instruments feature non-contact, linkage-less technology. DVC2000 instruments give local indication of valve travelposition and pressure status in one of 7 languages. No other control valves offer the innovation, technology and reliability of digital Fisher GX valves.Integrated Digital TechnologyA typical GX configuration features the FIELDVUE DVC2000 digital valve controller. The industry-leading FIELDVUE digital valve controller brings easier control, enhanced performance and unduplicated maintenance advantages to control valve applications.™ digital plant As such, they present critical operating information about themselves and the process to enable plant personnel to make better-informed decisions.The PlantWeb digital plant architecture offersproven improvements in system availability, reduced variability, increased throughput and enhanced product quality.You told us what you wantedEasy to MaintainThe GX is robust and compact. Its design architecture features common parts across all sizes, which reduces spare parts inventory requirements and associated costs.Actuator removal is quick and easy. The actuator can be easily field reversed to a fail-open or fail-closed configuration.The digital GX with integrated DVC2000 features linkage-less, non-contact position feedback, which eliminates mechanical wear between the valve and instrument. The digital GX features an integral interface to eliminate tubing for most applications, further simplifying maintenance issues found in most control valve assemblies today. The one-piece packing follower threads into the bonnet to simplifyinstallation and adjustment of the packing system. The system employs live-loading to compensate for normal wear.Certified Emission Control Packing SystemThe GX, with its live-loaded emission control packing system, gives you a single valve that you can use effectively in a wide variety of applications. It meets elevated temperature requirements, up to 371°C (700°F), and can handle rigorous mechanical and thermal cycles.Live-loaded emissioncontrol packing is standardin the GX. Choose eitherPTFE V-ring or graphiteULF (ultra low friction).The GX with live-loadedgraphite ULF packing isavailable for all sizes andis standard on the HT (high temperature) construction. It is compliant with both the TA-Luft and ISO (DIS) 15848-1 classB emission control packing standards. Complianceto these standards was tested and certified byTÜV (TA-Luft) and Cetim (ISO 15848-1) third party agencies. Contact your local sales office for copies of your GX emission control packing system third party certifications.The GX emission control packing system provides low friction and precise guiding for optimized control valve performance throughout the life cycle of the control valve. It maintains superior stem seals to reduce fugitive emissions.The innovative stem connection technology within the GX valve ensures stem and packing alignment for superior sealing and extended service life. Bellows Extension BonnetThe GX bellows extension bonnet provides reliable and tight stem sealing for those applications where emissions escaping to the environment cannot be tolerated. The GX bellows is available in SST (1.4571 / 316Ti) or N10276 and covers a full range of valve sizes from DN 15 through DN 100 (NPS ½ through 4).The GX bellows system has been designed for100,000 full-travel cycles at maximum allowable pressure and ambient temperature (20°C [68°F]).The mechanically-formed metal bellows provides high operating reliability and extended cycle life.Tight Stem Sealing The GX bellowsdesign incorporates a rugged double-or triple-wall construction for addedsecurity. Each bellows has beentested with helium before itleaves the factory.Dramatic Improvement in Temperature Controllability: GX 3-WayWith its unique flow cavity and integrated FIELDVUE digital valve controller technology, the GX 3-Way valve provides consistent temperature control for a wide range of operations, including heat exchangers and lubricating skids. Its high capacity design and precise linear characteristics allow for accurate temperature control.The GX 3-Way valve is multi-faceted in its abilityto cover both flow mixing (converging) and flow splitting (diverging) applications with no extra parts needed. Unlike other 3-way valves, it features both side-port and bottom-port common trim. The high-temperature, side-port common trim utilizes an unbalanced plug design, a stem extension, a yoke extension, and includes live-loaded ULF graphite packing and a hard-faced seat ring.The GX 3-Way’s compact size matches easily to your piping. The integrated FIELDVUE digital valve controller mounting as well as GX parts commonality contribute to a lower parts count for reduced inventory and maintenance costs. The seat ring and one-piece plug and stem provide easy maintenance. As with the GX, the GX 3-Way requires no actuator sizing once the valve body construction is selected. The GX actuator platform is common across all GX valves, both 2-Way and 3-Way.Compact GX 3-Way Valve The Fisher GX 3-Way is a state-of-the-art control valve and actuator system, designed to accurately control water, oils, steam, and other industrial fluids.

Terminals 4 and 6 need to be wired separately.62Isolation relays must be used in parallel connection of multipleactuators using a common control signal inputs. The relays should be DPDT.63Isolation relays are required in parallel applications. The reason parallel applications need isolation relays is that the motor uses two sets of windings, one for each direction. When one is energized to turn the actuator in a specific direction a voltage is generated in the other due to the magnetic field created from the first. It’s called back EMF. This is not an issue with one actuator because the voltage generated in the second winding isn’t connected to anything so there is no flow. On parallel applications without isolation, this EMF voltage energizes the winding it is connected to on the other actuators in the system, the actuators are tying to turn in both directions at once. The EMF voltage is always less than the supply voltage due to the resistance of the windings, so while the actuator still turns in the commanded direction, the drag from the other reduces the torque output and causes overheating.!WARNING! LIVE ELECTRICAL COMPONENTS!During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.SY4-24MFT Technical Data SheetModulating, Non-Spring Return, 24 V, for DC 2...10 V or 4...20 mAD a t e c r e a t e d , 12/20/2019 - S u b j e c t t o c h a n g e . © B e l i m o A i r c o n t r o l s (U S A ), I n c .。

Fisher FIELDVUE数字控制阀控制器说明书

Supplement to HART r Communicating Fisherr FIELDVUE t Digital Valve Controller InstructionManualsFIELDVUE Digital Valve Controller Split RangingProcesses requiring extended rangeability may use two or more control valves. The first valve operates over the firstportion of the range. When the first valve is nearly 100% open, the control action begins to open the second valve. This is called split ranging. When split ranging is performed a single signal from the control system is supplied to the valve actuators. This single signal is split among the positioning devices on each valve. The positioning devices are used to achieve full valve travel over the reduced input range. Most applications need a predictable overlap region in the middle of the signal range to avoid a zone of no control. Positioning devices provide accuracy to ensure the correct overlap exists.When split ranging FIELDVUE digital valve controllers, each device requires a minimum voltage available at the instrument terminals of at least 12 volts (See the appropriate instruction manual for details). Many control systems provide a compliance voltage that is less than the minimum requirement of 24 volts for two instruments wired inseries. This supplement describes two methods to address the potential discrepancy between the compliance voltage and the requirements of FIELDVUE instruments.Limitations of Split Ranging FIELDVUE Digital Valve ControllersSplit ranging FIELDVUE digital valve controllers provides the following limitations:D Most control systems cannot provide the 24 volt compliance voltage. A device to boost the compliance voltage may be required, such as the Action Instruments Action Pak R AP4380-2000.D To communicate with multiple HART instruments on one pair of wires may require the polling addresses for the instruments be nonzero. This means the instrument polling addresses must be reset and the HART devices (either the 475/375 Field Communicator or ValveLink software with a HART modem) must be programmed to poll for instruments at polling addresses other than zero.D Use of the HART Tri‐Loop t is limited to communication with only one instrument.D The instrument polling addresses may be nonzero, thus limiting communication with a HART multiplexer.Guidelines for Split Ranging FIELDVUE Instruments1. Check the voltage available at the instrument terminals using the method in the instrument instruction manual.2. Verify that the control system compliance voltage is at least 24 volts DC at 20 mA output. If the compliance voltage is less than 24 volts DC, add a device to boost the compliance voltage (such as the Action Instruments ModelAP4380‐2000). (Note: the AP4380‐2000 does not have any hazardous area approvals. Appropriate non‐hazardous installations should be selected.)3. Verify that cable length will not limit HART communication. See the instruction manual for details.4. For intrinsically safe installations, install approved intrinsic safety barriers between the non‐hazardous andhazardous areas.Methods of Split RangingTwo methods are available for split ranging FIELDVUE instruments: the traditional method and an alternate method.Traditional MethodThe traditional method uses the traditional split‐range wiring where the two instruments are connected in series to a single pair of wires from the control system, as shown in figure 1. With the traditional method:D The device used to boost the compliance voltage may be required to operate beyond its specifications.D To communicate with multiple HART instruments on one pair of wires requires the polling addresses for the instruments be nonzero. This means the instrument polling addresses must be reset and the HART devices (either the 375 Field Communicator or ValveLink Software with a HART modem) must be programmed to poll forinstruments at polling addresses other than zero.D Because the instrument polling address for one of the instruments must be nonzero, communication with a HART multiplexer is not possible.D Use of the HART Tri‐Loop is limited to communication with only one instrument. In addition, because the default polling address for the Tri‐Loop is one (1), the instrument polling addresses must be set in the range of 2 to 15.Alternate MethodThe alternate method requires more field wiring, but this method:D Allows the device used to boost the compliance voltage to operate within its specifications because it supplies a single instrument.D The polling addresses can remain at zero (0) because the two instruments are not on the same HART loop.D Allows communicating over a HART multiplexer network.D Multiple Tri‐Loops may be used allowing multiple instruments to operate in burst mode.D Split ranging with more than two FIELDVUE digital valve controllers is possible. Installation—Traditional MethodWhen connecting two instruments in series for a split range application, the compliance voltage must equal at least 24 volts DC. This is generally impractical with most DCS controllers, but quite possible with older analog controllers. For example, a Fisher TL108 controller with 45 volt DC power supply provides a compliance voltage of 27 volts DC at 20 mA output and a C master of 10,000 pF. For other controllers or DCS systems, an Action Instruments AP4380-2000 isolator or other similar device may be used to increase the compliance voltage.The published compliance voltage of the AP4380‐2000 is less than 24 volts DC. However, typical compliance voltage for this isolator is much higher. To ensure sufficient compliance voltage, the Action Instruments distributor can check2compliance voltage of the AP4380-2000 prior to shipment. This should be done using the technique described in the instrument instruction manual. Generally, a compliance voltage of 25 volts DC at 20 mA output with a guaranteed line voltage of 120 volts AC is adequate for normal lengths of field wiring.Wiring Hook‐UpThe Action Instruments product bulletin describes the product details and limitations (available on the web at ). These should be read and observed. Before installation, configure each instrument with different HART polling addresses (example HART polling addresses 2 and 3). The connections are shown in figure 1. A typical installation has the control system 4‐20 mA DC output signal connected to the AP4380-2000 input terminals. The isolator can be installed in the rack room. Connect the 4‐20 mA DC output from the AP4380‐2000 to the field wiring. In the field, connect the AP4380‐2000 positive (+) output terminal to the first FIELDVUE instrument LOOP + terminal. Connect the first FIELDVUE instrument LOOP - terminal to the second FIELDVUE instrument LOOP + terminal. Connect the second FIELDVUE instrument LOOP - terminal to the AP4380-2000 negative (-) output terminal.Figure 1. Typical Installation Schematic, Traditional MethodConfigurationCurrent flowing through the input terminals of the isolator is regenerated at the output terminals of the isolator (at a higher voltage) and flows through both FIELDVUE instruments. Input ranging of the FIELDVUE instruments is easily changed without recalibrating. This is done by configuring the Input Range Low and the Input Range High to the desired values. A typical configuration would be:FIELDVUE Instrument Input Range Low Input Range High Polling Address#1 #24 mA12 mA12 mA20 mA233Installation—Alternate MethodWhen connecting two instruments in series for this split range application, the compliance voltage requirement from the DCS controller is much lower. This is because the Action Instruments AP4380‐2000 is in series with the first FIELDVUE instrument and requires minimum voltage (0.3 volts). The isolator powers only the second FIELDVUE instrument and therefore provides adequate voltage.Wiring Hook‐UpThe Action Instruments product bulletin describes the product details and limitations (available on the web at ). These should be read and observed. The connections are shown in figure 2. For a typical installation, connect the control system positive (+) output terminal to the AP4380‐2000 positive (+) input terminal. Connect the AP4380‐2000 input negative (-) terminal to the first FIELDVUE instrument LOOP + terminal. Connect the first FIELDVUE instrument LOOP - terminal to the control system negative (-) terminal. Connect the AP4380‐2000 positive (+) output terminal to the second FIELDVUE instrument LOOP + terminal. Connect the AP4380‐2000 negative (-) output terminal to the second FIELDVUE instrument LOOP - terminal.Figure 2.

A typical configuration would be:FIELDVUE Instrument Input Range Low Input Range High Polling Address#1 #24 mA12 mA12 mA20 mAMultiple Split RangeThe installation described for the alternate method can be extended to multiple instruments, as shown in figure 3. This architecture allows up to four units to be split ranged. Due to an increase in the signal to noise ratio as the input span decreases, the minimum input span should be limited to 4 mA. Be aware that as the number of units to be split ranged increases, the accuracy of each unit is affected.Figure 3.

Parker FRC电动阀门控制系统说明说明书

Parker FRC电动阀门控制系统说明说明书

Principle of Operation:The need to remotely control process flow electrically using high pressure multi-turn needle valves has long been sought.Pneumatic control of this type is an engineering challenge and cost prohibitive. Parker Autoclave Engineers solves these issues with our FRC line of electric actuators. When mated to our Regulating Stem Needle Valves and sent a 4-20mA signal, this actuated valve system provides precise control when needed and even provides enough torque to close the valve when not needed. This valve/actuator combination is capable of controlling Liquid or Gas flows.The FRC Electric Actuator uses a 4-20mA input signal to turn the valve a programed amount of turns from fully closed to fully open (typically 5 turns) while also providing a position feedback using an independent 4-20mA signal. It is also capable ofclosing the valve completely when a 4mA signal is received. Should power be lost, the valve will freeze and “remember” it’s last position and will not need to be re-zeroed. The FRC actuator is designed to work with a number of Parker Autoclave Engineers Needle Valves from 1/8" to 3/4" tube sizes and up to 60,000 psi (4140 bar) using the Regulating Stem option - see individual valve brochures for Cv and Flow Curves.Features:• Designed for Multi-turn Needle Valves, tubing/pipe sizes 1/8" to 3/4"• Precise, accurate control using Regulating Stem option.• Operational Temperature Range: -40° to 160°F (-40° to 70°C) - Valve temperature not to exceed 600°F • Closing Torque capable of up to 60,000 psi (4140 bar) operation• Weatherproof or Explosionproof (CSA approved Cls 1, Div 1 Grps B, C & D)• Maximum Rotation Speed: FRC1 = 4 sec/turn, FRC2 = 15 sec/turn (5 turn open/close)• Weatherproof Enclosure is supplied with TURCK 5 position cable connector and 20’ of cableNeedle Valve ActuatorsModel FRC - Electric, 24 VDCFlow Regulating Control/Shutoff10V2, SW, SM, VM SeriesNeedle Valves to 60,000 psi (4140 bar)2Needle Valve Actuator: Model FRC - Electric Flow Regulating Control/Shutoff 02-9336SE 0421Specifications and Ordering Guide:Electric ActuatorElectrical Specifications:• Electrical Input: 24VDC only, 72 Watt maximum • Control Input: 4-20mA• Position Feedback: Independent 4-20mA • Position Detection: Hall Sensors • Motor: BLDC brushless DC motorMechanical Specifications:• Standard Enclosure - EPD Coated NEMA 4/IP65 Equivalent • Optional Anodized Aluminum Explosion-Proof Enclosure, Nema 8/IP67, CSA Approved for Class 1, Division 1, Groups B, C, D / T6 Areas• 500+ Positions per turn (+/- 0.25° Position Accuracy), 3243 Actuator Positions over Full Span• Maximum Rotation Speed: #1 Actuator = 4 sec/turn (5 turn open/close), #2 Actuator (high torque) = 15 sec/turn (5 turn open/close)• Actuator Operating Temperature -40°(-40°C) to160°F(70°C), Valve Temperature not to exceed 600°F • Actuator life Expectancy: 250,000 cycles • Gears and Bearings are Lifetime Lubricated• 20 ft. cable included with 6 pin/5 wire connector (FRC1 and FRC2 Weatherproof version only)• Wiring Terminal, Maximum Wire Size: 18 Gauge (To Terminate larger gauge wire, see Option Code XPFL below)Position on Powerloss:• Remembers Last Position•Reseats Valve if Current is Between 3.0 and 4.16mAOrdering Guide:(reference individual Valve Series brochure for exact valve detail)20SM9882-FRC2XTG = 20SM Series Needle Valve, 20,000 psi MAWP , 9/16” MP Cone and Thread, 2-way Angle/Replaceable Seat Valve, Flow Regulating On/Off Explosion Proof Actuator/High Torque, PTFE Glass packing to 600°F max.Note: Actuators can be rotated to any one of four compass locations.
