YT-1000L series electric-pneumatic valve is a device that delivers an air signal to a pneumatic actuator to control the position of a valve. Convert the DC current signal output by the control system into the gas signal that drives the regulating valve to control the action of the regulating valve.
YT-1000L series electric-pneumatic valve locator is a device that receives DC current signal 4-20mA from the controller or the control system,and the precisely controls valve opening through pneumatic actuator.
All valve positioner manufactured by HEARKEN are individually tested, Testing is carried out to check the leakage in both internal and external, All bodies are stamped with year,month of production size and serial number.
