Pneumatic Valve Locator
Features
Pneumatic Valve Locator
ZPQ type pneumatic valves locator is main matching meter in industrial automation of pneumatic actuators, can be used for improving valve position of linearity, overcome the stem friction and eliminate regulator unbalance force influence etc, so as to ensure the valve position according to the regulative instrument 20-100KPa air pressure signal proportional relation, realizing correct positioning. Pneumatic valves locator can match pneumatic actuators, also can be quipped with pneumatic piston actuators, can match straight travel, also can configure angle stroke regulating actuator. Therefore, Shanghai Enine pneumatic valves locator is widely used in petroleum, chemical, metallurgical, power, textile, paper and other industrial automation, is the indispensable product in industrial automation instrument.
