Name:electric-pneumatic valve positioner

Model:ZPD series

Quoted price:面议

Feature:ZPD electric-pneumatic valve positioner

electric-pneumatic valve positionerDetails:

ZPD series electric-pneumatic valve positioner
positioner is auxiliary instruments used with pneumatic adjusting valve, receive DC signal from electric regulating instruments and convert the signal to corresponding pneumatic signal, control adjusting travel. By the action of feedback system , make the travel and signal change proportionally, then ensure the correct position of valve. If used with positioner, can overcome the friction of valve stem, speed up the movement of valve. Widely used in oil、chemical、metallurgy、power station and textile automation system of industries
Structure principle
Mainly made up of shell, torque motors, zero body, nozzle - tailgate, junction box
Designed according to torque balance principle
