Valve Positioner

Listing ID #4285359

Valve Positioner is designed to operate rotary or linear pneumatic valve actuator.through the pneumatic actuator,the positioner control the valve to the required position when collecting standard electrical current signal or computer signal.This Valve Positioner includes piezo and pilot valve,inductive position sensor and control CPU etc..
The principal is different from the traditional electro-pneumatic valve positioners which use nozzle flapper structure.Advanced PID fuzzy control software in the CPU,auto adapting parameter of PID.it makes the control fast,steady and exact letter LCD version and four push buttons meet all the requirements of parameter input,zero and span adjusting or split range.The valve position adjusting could be done without any other instruments at the working place.
