Elektro-pneumatischen Stellungsregler

This series of valves locators is the main fittings of all sorts of pneumatic actuators.It is used with pneumatic-valve,constitute a closed-loop and control loop.In order to improve the control precision.It can overcome the force of friction of the stuffing box and stem,it also can overcome the unbalance force of the medium difference pressure of regulator valve.It can improve valve movement speed and realize points process control.It can change the way of valve role and control each type of pneumatic actuators of the standard operating pressure.
