2/2 way Proportional Valve (motor-driven)
Universal controller Type 8611
The motor’s power consumption to hold a speci? c opening position of the valve is zero.
This key feature can reduce the energy consumption of a plant dramatically and thus make it more e?  cient.
Type 3285 is available as a standard ON/ OFF or proportional valve,
tput via the M12 circular plug-in connector
這一特性可大幅度降低設(shè)備對(duì)能源的需求，從而使其更為*效。
型號(hào) 3285 有比例閥標(biāo)準(zhǔn)款、帶集成式位置調(diào)節(jié)儀的規(guī)格
以及帶集成式過(guò)程調(diào)節(jié)器的規(guī)格三種可選。
非介質(zhì)接觸式驅(qū)動(dòng)器
 as a version with integrated positioner and as a version with integrated process controller.
The positioner proportional valve converts an external standard signal (position set-point value) into a valve position.
 The position of the actuator is controlled according to the position set-point value.

直接作用式比例閥型號(hào) 3285 適用于在密封式或開(kāi)放式調(diào)節(jié)回路中計(jì)量液體和氣體。
The current position (POS) of the electromotive valve is recorded by the position measuring system.
The position controller compares this position actual value to the set-point value (CMD) speci? ed as the standard signal.
In case of a control di? erence (Xd1), the motor control signal is sent to the actuating drive as the actuating variable.
Z1 is a disturbance value. Both valve end positions are indicated by the LED status.
 Moreover, the position actual value recorded using the position measuring system is ou

閥門(mén)通過(guò)步進(jìn)電機(jī)驅(qū)動(dòng)。
集成式電子裝置顯著簡(jiǎn)化了流程一體化，并且不需要使用額外的控制模塊。
夾持特定的閥門(mén)孔眼時(shí)，電機(jī)不需要能源。
2) Characteristic data of control behaviour depends on process conditions
 The direct-acting motor valve of type 3285 is used for dosing of liquids
and gases in closed or open control loops.
The valve features a stepper motor as the actuator.
The integrated electronics simpli? es the process integration;
additional actuation modules are not necessary.
