The actuator has some special features:• it automatically adapts its stroke to the valve end positions which reduces commissioning timeOrdering • valve flow adjustment feature; flow can be variably-adjusted from linear to logarithmic or opposite.• the advanced design incorporates load related ‘switch-off’ to ensure that actuators and valves are not exposed to overload Main data:• Nominal voltage (AC or DC): - 24 V, 50 Hz/60 Hz • Control input signal: - 0(4)-20 mA - 0(2)-10 V • Force: 400 N • Stroke: 20 mm • Speed (selectable):- 7.5 s/mm - 15 s/mm• Max. medium temperature: 120 °C • Self calibrating • LED signalling• External RESET button • Output signal • Manual operationTechnical dataAccessories-AdapterTypefor valve’s DNfor Actuator Code No.AB-QM adapter (2st generation)40-100AME 15 QM003Z0694AB-QM adapter (1st generation)AME 435 QM065Z0313Power supply V 24 AC/DC; ±10%Power consumption running VA 4,5standby1,2Frequency Hz 50/60Control input Y V 0-10 (2-10); Ri = 95 kΩmA 0-20 (4-20); Ri = 500 ΩOutput signal X V 0-10 (2-10); RL = 650 Ω (maximal load)Closing force N 400Max. stroke mm 20Speeds/mm 7,5 or 15Max. medium temperature °C120Ambient temperature0 … 55Storage and transport temperature –40 … 70Protection class II Grade of enclosure IP 54Weightkg 0,45- marking in accordance with standardsLow Voltage Directive (LVD) 2006/95/EC: EN 60730-1, EN 60730-2-14 EMC Directive 2004/108/EC: EN 61000-6-2, EN 61000-6-32VD.CV.S2.02 © Danfoss 09/2014SMT/SIData sheetActuator for modulating control AME 435 QMInstallationMechanicalNo tool is required to mount actuator on the valve. Installation of the valve with the actuator is allowed in horizontal position or upwards. Installation downwards is not allowed.The actuator must not be installed in anexplosive atmosphere, at ambient temperature lower than 0 °C or at ambient temperature higher than 55 °C. It must not be subject to steam jets, water jets or dripping liquid as well.Note:The actuator may be rotated up to 360° withrespect to the valve stem by loosening the retaining fixture. Once the actuator is placed, retighten the fixture.ElectricalElectrical connections can be accessed by removing the actuator cover. Two cable gland entries without thread (Ø16 and combined Ø16/Ø20) are prepared for cable glands. From factory one entry is provided by rubber cable gland and the other entry is prepared for opening. Note:Cable and cable gland used must not compromise the actuator’s IP rating, and must ensure the connectors are fully strain relieved.Rubber cable gland delivered from factory does not compromise IP rating but it does not provide fully strain relieve according to LVD directive.Please observe local rules and regulations as well.Complete the mechanical and electricalinstallation, set jumper and DIP-switches, then perform the necessary checks and tests:• Apply powerNote that the actuator will now perform automatic Calibrating function • Apply the appropriate control signal and check:- SW7 setting- the actuator drives the valve over the entire stroke length The unit is now fully commissioned.CommissioningAutomatic Calibrating featureThe actuator automatically adapts its stroke to the valve end positions :- when power is applied for the first time or - afterwards by pressing the STAND BY/RESET button for 5 seconds Testing entire valve stroke lengthThe actuator can be driven to the fully-open or closed positions by connecting SN to terminals 1 or 3.The actuator must be dismantled and the elements sorted into various material groups before disposal.Disposal3VD.CV.S2.02 © Danfoss 09/2014SMT/SIData sheetActuator for modulating control AME 435 QMEqual-percentage valve-flow adjustment (SW 7 in position ON )The actuator has a special valve-flowadjustment feature called alpha value. Actuator characteristics can be, by turning the alpha knob counter clockwise (CCW), variably-adjusted from α=1 (linear) to α=0.1.Jumper/DIP switch settingJumper• U/I - Input signal type selector- U position; voltage input is selected - I position; current input is selected Factory setting: jumper is in U position.DIP switchesFactory setting: all switches are in OFF position.• SW 1: Not used• SW 2: Input signal range selector- OFF position; the input signal is in the range from 0-10 V (voltage input) or from 0-20 mA (current input)- ON position; the input signal is in the range from 2-10 V (voltage input) or from 4-20 mA (current input)• SW 3: Direct or Inverse acting selector- OFF position; the actuator is in direct acting mode (stem extracts as voltage increases)- ON position; the actuator is in inverse acting mode (stem retracts as voltage increases)If used with AB-QM valves, SW 3 is recommended to be in OFF position (factory setting).• SW 4: Fast/Slow - Speed selector- OFF position; the actuating speed is 7.5 s/mm• SW 6: Not used• SW 7: LOG/MDF - Logarithmic or modified flow through valve selector- OFF position; .........LOG (α=0.2, factory setting)- ON position; ...........MDF (initial setting: α=1, linear)Explanation:If SW 7 is in OFF position, alpha knob is not activated. Turning alpha knob will not influence α value (α=0.2).If SW 7 is in ON position, α value can be manipulated using alpha knob. MDF initial setting of alpha knob is 1, which means linear setting. Regarding alpha knob setting In order to have optimal control, linearcharacteristics of system (valve, actuator, HEX) is required. This can be assured using theright α value. Appropriate α value depends on temperatures of heating/cooling medium and controlled temperature of heated/cooled medium. Calculate α value according to the Tech Note number VNHUA102 (Setting the right α value).4VD.CV.S2.02 © Danfoss 09/2014SMT/SIData sheetActuator for modulating control AME 435 QMLed signalling/Actuator operating modesLED function indicatorThe bi-colour (green/red) LED function indicator is located on the actuator cover. It indicates the operating modes.External buttonActuator has external STAND BY/RESET button which is located next to LED indicator. By pressing on this button different operating modes are initiated:• Calibrating modePressing the STAND BY/RESET button for 5 sec. causes the actuator to start Calibrating procedure :The bi-colour LED flashes green at 1 sec.intervals during calibration procedure, which begins by extracting the stem. When the maximum force is detected (at the end valve position), the actuator then retracts thestem, until the maximum force is once again detected (on the other valve end position). The actuator will then enter to normal mode and respond to the control signal.• Positioning modeThe bi-colour LED is green and stays onduring positioning of the actuator according to the control signal • Normal modeWhen the positioning of the actuator is finished the LED flashes green every 6 seconds.• STAND BY modePressing the STAND BY/RESET button switches the actuator to STAND BY mode. The actuator keeps its last position in this mode and does not react to any control signal. This mode can be used for manual operation during the commissioning of other equipment, or for service purposes.The bi-colour LED flashes red at 2 sec. intervals.After pressing the STAND BY/RESET button again actuator switches to normal mode.5VD.CV.S2.02 © Danfoss 09/2014SMT/SIData sheetActuator for modulating control AME 435 QMManual overrideManual override is done by means of control knob on actuator housing:• Disconnect power supply or press STAND BY/RESET button• Adjust valve position using the control knob (observe the rotation direction)When manual override is not needed:• Restore power supply or press STAND BY/RESET button again Remark:When the manual override has been used, the output signal (X) is not correct until the actuator reaches its end position.Wiring 24 VAC/DC onlySP 24 VAC/DC ..............

丹佛斯pm主阀原理
丹佛斯PM主阀是一种控制多个设备的减压控制阀,它能够控制多个设备的压力以确保运行的稳定性和安全性。
它工作原理是,当设备的压力超出预设上限时,PM主阀就会开启,以排出多余的压力,以防止设备的运行状况受到不良影响。
丹佛斯PM主阀是一种纯电磁阀,由电磁马达驱动,可以根据不同的压力配置实现减压控制,也就是说可以控制低于预设压力的最大值。
当设备压力逼近预设压力时,PM主阀会自动开启,以取得最佳节能效果。
此外,PM主阀还具有良好的阻尼效果,能够缓冲压力变化,防止因过大的压力变化而影响设备的性能和使用寿命。
丹佛斯PM主阀的另一个优点是其独特的带电磁的设计。
这种设计使其能够监测和控制压力,而无需人工介入。
它还可以让操作变得更加有效率,因为它能够根据不同的压力状态智能地调节阀门的位置,而不需要人工操作。
总之,丹佛斯PM主阀是一种高效且安全的压力控制阀,它能够用于减压控制多个设备,从而确保风机、发动机和气动设备的良好运行,提高工作效率。
此外,它还具有简单易操作、节能环保等特点,是工业设备的理想选择。

丹佛斯-AKS-ICAD-EKC电动阀使用说明书
●待所有参数均设定完毕后,放开所有按键,一段时间后,显示自动恢复到原始画面。
注意:显示r12等设定项后,同时按住两键进入参数设定状态,通过按上下两键调定具体设定值,参数值设定完毕后,务必再次同时按住两键进行确认。
LED显示:当前实际液位值,按一下“下按键”,则LED显示为电动阀开度。
二、AKS41液位传感器操作指南
测量范围
出厂设定:杆子的出厂时是根据R717设定的,输出4~20毫安的信号对应杆子的整量程。任何的液面扰动会被传感器内部屏蔽。
R717(NH3)
可以使用出厂设定,不必更改。
R22/R404A/R134a/R744(CO2)
必须根据不同制冷剂进行设定,设定步骤请参照下一节。
5、切断AKS41的电源,设定就会被保存。如果您需要重新设定,重复步骤1,2,5。
信号屏蔽
信号屏蔽的出厂设定为15秒,设定可以通过按设定键改变,范围是1~120秒。也可以在系统运行时改变设定,步骤为:
1、接通电源。
2、按设定键,每按一下屏蔽时间增加1秒。例如:1下=1秒;2下=2秒;……,120下=120秒;121下=120秒。
绿灯闪四下……输出信号为8毫安=R134a
绿灯闪五下……输出信号为9毫安=R744
3、再按设定键,选择制冷剂。
按一下5毫安=R717(出厂设定)
按两下6毫安=R22
按三下7毫安=R404A
按四下8毫安=R134a
按五下9毫安=R744
4、当选到所需制冷剂时,等10秒钟到绿灯一直亮着(不闪了),这时表明已经选到所需的制冷剂了。

如何实现盘管散热量和阀门开度的线性关系
由于盘管静特性为指数特性,因此为了 达到良好的受控效果,通常采用对数型曲线 的调节阀。只有保证一定的阀权度,才能保 证阀门的实际曲线符合要求。由于盘管静特 性与供水水温差有关,因此,小温差对于这 个问题更敏感,所以这个问题在夏季空调设 计中尤为重要,否则,系统稳定时间过长。

驱动器的选型原则
后存在着压差,因此对于有一定面积的阀芯来说,存在着一个力,驱 动器提供的驱动力必须大于这个力才能将阀门完全关闭,因此选择驱 动器时要按照最大关闭压差进行选择,如下表,对于相同的阀体 VRG 选择AME25时可以适应的最大关闭压差为3Bar。 或VRB DN50 ,选择AME15时可以适应的最大关闭压差为 1Bar,
