The material of the body and bonnet is A6063, and other metal components of the vacuumpart are made of SUS304. The sealing material of the vacuum part is FKM as standard, but this can be changed to other materials (refer to “How to Order”). Confirm whether the fluid to be used is compatible with the materials before use.Grease for vacuum is applied to the sliding part of the vacuum (Fluorine grease: Y-VAC2).2. Select materials for the pilot pressure piping and fittings whose heat resistance is suitable forthe applicable operating temperature.●Models with auto switch1. Keep the temperature of the switch below 60o C●With heater (thermistor)1. When using a model with a heater, a mechanism to prevent overheating should beinstalled.SelectionCaution●All models1. When controlling valve responsiveness, take note of the size and length of piping, as wellas the flow rate characteristics of the actuating solenoid valve.2. Keep the pilot pressure within the specified range.The specified range of XLG-16, XLG-25 and XLG-40 is from 0.3MPa to 0.5MPa, and that is for XLG-50, XLG-63, XLG-80, XLG-100 and XLG-160 is from 0.4MPa to 0.5MPa.3. Keep within the specified range of the pilot pressure.●High temperature type1. If using gases that cause a large amount of deposits, heat the valve body to prevent depositsin the valve.Mounting● All models1. In high humidity environments, keep the valve packed until the time of installation.2. For models with switches, secure the lead wires so that they have sufficient slack, withoutany unreasonable force applied to them.3. Perform piping so that excessive force is not applied to the flange sections. When there isvibration from heavy objects or attachments, etc., fix piping so that vibration will not apply torque directly to the flange section.4. Vibration resistance allows for normal operation of up to 30 m/s2 (45 to 250Hz), butcontinuous vibration may cause a decline in durability.Arrange piping to avoid excessive vibration or impacts.●High temperature type (temperature specification / H0 H4 H5)1. In models with a heater (thermistor), take care not to damage the insulation components of thelead wires and connector section.2. The set temperature for models with a heater should be established without any drafts or heatinsulation. It will change depending on conditions such as heat insulation measures and the heating of other piping. Fine adjustment is not possible.3. When installing heater accessories or mounting a heater, check insulation resistance at the actual operating temperature. A current leakage breaker or fuse should be installed.4. If the valve is to be insulated, only the body should be insulated, excluding the bonnet part.5. In models with a heater, when the heater is in operation, the entire valve becomes hot.Be careful not to touch it with bare hands, as burns will result.1. Before mounting, clean the surface of the flange seal and the O-ring with ethanol, etc.2. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it should be handled so that the seal surface is not damaged in any way.If the fluid or reaction product (deposit) may cause the valve to become unsafe, the valve should be disassembled, cleaned and re-assembled by an operator who has sufficient knowledge and experience (e.g. a specialist).1. When removing deposits from the valve, take care not to damage any part of it.2. Replace the bonnet assembly when the valve is approaching the end of its service life.* For details regarding endurance cycles, please reference Section 5 of this Operation manual titled Period and scope of warranty . (pages 12)3. If damage is suspected prior to the end of the service life, perform early maintenance.4. SMC specified parts should be used for service. Refer to the Construction / Maintenanceparts table.5. When removing the valve seal and external seal, take care not to damage the sealingsurfaces. When installing the valve seal and external seal, be sure that the O-ring is not twisted. (Refer to Section 6 Parts Replacement Procedure (pages 13 to 15) for details.) WarningSMC specified parts should be used for service.Refer to the construction drawing.1. Replace the bonnet assembly when changing the sealant material. Due to the differentmaterials used, changing only the seal may prove inadequate.Bonnet assembly (Construction part no.) 1Temperature SpecificationsValve size16 25 40 50For generalenvironments XLG16-30-1 XLG25-30-1 XLG40-30-1 XLG50-30-1-1 For hightemperature XLG16-30-1H XLG25-30-1H XLG40-30-1H XLG50-30-1H-1TemperatureSpecificationsValve size63 80 100 160For generalenvironments XLG63-30-1-1 XLG80-30-1-1 XLG100-30-1-1 XLG160-30-1-1 For hightemperature XLG63-30-1H-1 XLG80-30-1H-1 XLG100-30-1H-1 XLG160-30-1H-1 Note1) The magnet for auto switch is not provided.

Thesethermistors self regulate their temperature byswitching the resistance at certain criticaltemperatures, so a separate temperature controller isunnecessary.If the temperature of the PTC heaters fitted exceeds200o C, then it may fail. The maximum operatingtemperature for the valve is 150o C. If the heatertemperature is over 200o C or valve temperature isover 150o C, please use thermostat to control theheaters to prevent overheating.With PTC type heaters, there is an initial surge ofcurrent (inrush current) after the power is supplied. These inrush current will reduce overtime. If multiple heater assemblies are used, the inrush current to the heaters will be magnified and care should be taken. When multiple heater assemblies or valves are used, do not apply power to the heater assemblies simultaneously. Keep approximately 30 seconds between applications of power toeach heater assembly. This will allow for incremental spacing to prevent harmful large initial surge.4.4-1.

气动三通阀门使用说明书及维修手册
TFMQ气动阀门（三通）使用说明书及维护手册无锡市中良设备工程有限公司目录一、气动阀门（三通）简图二、气动阀门（三通）的基本结构三、结构性能四、气动阀门（三通）的使用与保养五、故障的检查与维修六、气缸的安装与使用七、气缸的维护与保养二、气动阀门（三通）的基本结构气动三通阀门主要有箱体、翻板、摆杆、气缸、行程开关等组成。
三、结构性能阀门的箱体是阀门的主体，要有足够的刚度和强度，以保证与进料管和出料管的联结和承受自重和物料重，因此由8—10mm厚的钢板焊接而成，同时要保证翻板在其内不受刮、碰影响的翻转，供物料通过。
翻板是关闭和开通物料流量的主要部件，因此要求有足够的刚度、强度和耐磨性，因此选用8--14mm厚的钢板制成，为了保证耐磨性，在阀门体内侧板、翻板两面衬挂耐磨性好的聚氨脂板或65Mn 板，为了降低料流在翻板上的流速，在其上加横档板以降低流速，减少磨损。
四、气动三通阀门的使用与保养气动三通阀门在使用前，首先检查其内部有无异物，卡刮翻板，气源压力应达到额定气压，管路应严密无泄漏，压缩空气应干净，应有过滤器和油雾器，活塞杆、连杆应灵活自如。
连接点螺栓、螺母不得有松动，气缸不得有泄露，检查行程开关控制的位置是否合适，如不正确应调整行程开关的位置。
五、故障的检查与维修见下表：六、气缸的安装和使用要求1、气缸在安装前应首先检查气缸在运输时是否损坏，连接部件是否松动，调整好后再行安装。
2、安装时气缸活塞杆不得承受偏心载荷或横向载荷，应使载荷方向与活塞杆轴线一致。
3、无论采用何种安装型式，都必须保证缸体不变形，气缸的安装底座要有足够的刚度，不允许负载和活塞杆的连接用电焊焊接。
4、气缸水平安置时，特别是长行程气缸，用水平仪进行三点位置（活塞杆全部伸出、中间及全部退回）检验。
5、速度调整，首先将速度控制阀（单向节流阀）的开度放在调整范围的中间位置，随后逐渐调节减压阀的输出压力，当气缸接近预定速度时，即可确定工作压力，最终速度不至撞击气缸盖为宜。

danfoss三通阀门使用说明
danfoss三通阀门使用说明Danfoss三通阀门是指采用高强度不锈钢、合金、陶瓷等材料制成的一种阀门。
其主要特点在于强度高、耐磨损、寿命长。
特别适用于化工、石油、冶金、机械等行业。
本阀门的使用寿命一般为40-50年左右，在使用过程中如出现漏水等问题应及时检修，避免造成不必要的损失。
1. Danfoss三通阀门不允许用手直接接触阀门内的介质，否则将损坏阀门结构。
如必须接触时，应注意防止液体飞溅到阀体上，造成损坏。
当阀门开启时，手不能接触到阀门内部，请使用其它保护工具对阀门进行检修。
由于阀门内部泄漏或损坏引起阀门关闭不严密或停止工作时，使阀门处于关闭状态。
如操作不当将会造成泄漏或损坏阀门内部元件。
2.阀门安装前应检查各零件、管件是否完整以及内部有无油污、铁锈等。
在安装阀门前，必须先清洗管道和阀门，以免安装时出现卡塞等现象。
安装阀门时，应使阀门置于合适的位置。
阀门的密封面和球面之间的间隙应保持在1-2 mm内，以免影响密封效果。
在安装阀门前一定要将阀门打开检查密封是否完好。
在管道上安装阀门时应尽量减少阀门之间的距离。
阀门的安装方向应与管道上安装阀门时所选定的方向一致。
关闭时阀门应处于开启状态。
安装阀门后应进行检验，确保密封性能良好。
阀门应有良好的密封性能，且密封面不得有砂眼、气孔、裂纹、疏松和缩孔等缺陷，密封性能应符合表1-3要求。
3.在安装过程中应注意的是必须安装好法兰和垫片，以免阀门因振动、冲击而损坏。
如果没有法兰和垫片，可以安装在法兰上，也可以安装在阀门上。
安装时要注意法兰上与阀门壳体垂直、相互平行，在安装时应使阀门在水平位置，不能与管道平行以免影响阀门的密封。
安装法兰和密封垫片时应注意保证法兰的密封面和垫片压紧，以免阀门因振动、冲击而损坏。
Danfoss三通阀门使用说明对阀门各部位的安装要求严格执行下列规定：首先要进行预处理在阀门安装前应对管道和阀门内部进行清洗，检查是否存在污物、异物等杂质。
三通阀
三通阀一：三通阀的原理：三通阀阀体有三个通口，它和普通阀门不同的是底部有一出口，当内部阀芯在不同位置时，出口不同。
如阀芯在下部时，左右相通；如阀芯在上部时，右出口被堵住，左口和下口连通。
因为左口和右口不在一条水平线上。
二：三通阀的分类：三通阀按流体作用方式分为合流阀和分流阀，合流阀有两个入口，合流后从一个出口流出。
分流阀有一个流体入口，经分流后由两个流体出口流出。
三：三通阀的结构特点 ：1. 三通球阀一般采用两阀座结构，亦可根据使用要求采用四阀座结构。
三通球阀具有以下优点：☆ 球阀不受安装方向的限制，介质的流向可任意。
流体阻力小，其阻力系数与同长度的管段相等。
☆ 结构简单、体积小、重量轻、无振动，噪声小。
☆ 紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
☆ 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离控制。
☆ 维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
☆ 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
☆ 适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
2. 三通控制阀的结构与双座阀类似，但在三通控制阀中，一个阀芯与阀座间的流通面积增加时，另一个阀芯与阀座间的流通面积减少。
而在双座阀中，两个阀芯与阀座间的流通面积是同时增加或同时减少的。
3. 三通球阀按作用方式分单作用和双作用两种型式，单作用型式的特点是一旦动力源发生故障时，球阀将处于控制系统要求的状态。
4. 三通阀的气开和气关，只能通过选择执行机构的正作用与反作用来实现，而在双座阀中气开和气关，则可以直接通过将阀体或阀芯与阀座反装来实现。
5. 当三通阀用于需要流体进行配比的控制系统时，由于它能同时代替一个气开控制阀和一个气关控制阀，因此可以降低安装成本和减少安装空间。
6. 三通阀也可用于旁路控制的场所，例如一路流体需要经过换热器换热，另一路流体不需要经过换热器换热，当三通阀安装在换热器前时采用分流三通阀，当三通阀安装在换热器后时采用合流三通阀。

Wetted Materials:Body, Ball, End Caps: CF8M stainless steel.Stem: 316 stainless steel. Stem Seal: Fluoroelastomer.Seats, Body Seal, Thrust Washer, Packing: PTFE.Temperature Limits:-40 to 450°F (-40 to 232°C) CWP . 297°F (147°C) steam maximum.Other Materials:304 stainless steel, vinyl.INSTALLATIONGeneral Information for On-Site Installation - The valve may be fitted in any position in the pipeline. For automated operation, W.E.Anderson does recommend that the valve and actuator be installed vertically in case of valve leakage, although this is not necessary for proper operation of the valve. To prevent damage to the seats and ball surface, the pipeline must be flushed so that it is free of dirt, burrs and welding residues before installing the valve.Installation of Clamp End Valves -Use the proper clamp and O-ring for pressure range of application. Place the O-ring into the O-ring groove on the clamp end. Slide the valve between the clamp fittings while making sure that the O-ring remains in place. Install the clamp over both valve ends and clamp fitting to insure alignment. Tighten both clamps on each valve end. Check proper operation of valve (manually or with the actuator).The Series BV3HL Three-Piece Sanitary Ball Valve provideseasy replacement of gaskets, seals, and seats without any special tools. The swing-out design of the valve allows for the center section of the valve body to be replaced while leaving the ends clamped in place if necessary.The BV3HL uses a cavity filled design, which means that the ball can remain completely enclosed by the pure TFE seats, eliminating the chance of product entrapment. Combined with an investment cast 316L stainless steel casting, this series of valve is ideal for food, beverage, semi-conductor, or pharmaceutical applications.Superior leak protection is accomplished by using a live-loaded packing system featuring belleville washers. An ISO 5211mounting pad is provided for easy automation.OPERATIONManual Operation - To open or close the valve, turn the handle 90° (1/4 turn). Valve in OPEN position: the handle is parallel (in line)with the valve or pipeline. Valve in CLOSED position: the handle is perpendicular (crossed) with the valve or pipeline.Automated Operation -Valves with actuators should be checked for stem alignment. Most applications are direct mount to the actuator, greatly reducing any sideload or increased torque.Make sure that all insert adapters are properly placed on the valve stem and fully engaged in the actuator.©Copyright 2010 Dwyer Instruments, Inc.Printed in U.S.A. 2/10FR# R2-443348-00 Rev. 1Disassembling and Cleaning the Valve -CAUTION: Ball valves can trap fluids in the ball cavity when it is in the closed position. If the valve has been used with hazardous media, it must be decontaminated before disassembly or handling.WARNING:All persons involved in the removal or disassembly of the valve should wear protective gear such as eye and face protection, gloves, etc.Relieve the line pressure. Place the valve in the half-open position and flush the line to remove any hazardous material(s) from the valve.Replacing the Thrust Washer, Packing, and Seats -A repair kit is available for all valves comprising: seats, body seal, stem seal, thrust washer, and stem packing.NOTE:The Series BV3HL Sanitary Ball Valve is designed with belleville washers for automatic wear compensation. If there are signs of leakage from the stem, it is time to replace the stem packing and thrust washer.Before replacing the thrust washer, seats, and packing, the pipeline must be depressurized. Maintenance, removal and replacement of seats and seals is simple even if the valve is installed in line. By removing three of the body bolts and loosening the fourth bolt, the valve body can be swung out of line (see illustration 1.1). Seats, seals, gaskets and balls can be replaced without disturbing the pipe alignment.Bolt Tightening Specifications -The body bolts on the valve must be tightened evenly. Tighten the bolts by hand, then use a wrench to tighten bolts in diagonal opposition. See chart 1.2 for bolt torque specifications.WARRANTYThe Series BV3HL Sanitary Ball Valve is warranted from defects in materials and workmanship for (1) year from the date of purchase.In the unlikely event the valve should fail, the unit can be returned to the factory for warranty repair if the warranty period has not expired.
