ZPQ type pneumatic valve positionerDetailed product description：

Summary
The ZPQ type pneumatic valve positioner is used in conjunction with a regulating valve. It inputs air supply pressure to the actuator chamber of the regulating valve based on the output signal of the pneumatic regulator, enabling the valve core of the regulating valve to be correctly and quickly positioned, and provides feedback based on the valve opening.
