Designed with precision, Electro Pneumatic Valve Positioner we offer is high on demand in the national and international markets. Electro Pneumatic Valve Positioner provided by us is widely appreciated by the clients for low power and air consumption, short response time, high sensitivity, compact design and reliable performance. Moreover, we offer this Electro Pneumatic Valve Positioner with position transmitter. Clients can avail the same at market leading rates.

About Electro Pneumatic Valve Positioner :

  • APP8000 Serial smart valve positioner is developed for smooth operation of linear or rotary pneumatic valve actuator.
  • The positioner controls the valve to the necessary position when collecting standard electrical current signal or computer signal.
  • This smart valve positioner comprises of inductive position sensor, control CPU, piezo & pilot valve etc. besides others.
  • Through the use of pilot valve and advanced piezo valve of HOERBIGER-ORIGA company, the response time of piezo valve is below 2ms whereas the response time of pilot valve is under 20ms, thus leading to a very high adjusting precise and short response time of the valve.
  • When the valve reaches the required position, the air position could be overlooked as the position does not require air
  • The smart valve positioner is combined with the utility of performance monitor along with digit valve controller.


Principle :

  • Uses nozzle flapper structure
  • Advanced PID fuzzy control software in the CPU, auto adapting parameter of PID, it makes the control fast, steady and exact
  • 32 letter LCD version and four push buttons meets the precise requirements of parameters input, zero and span adjusting or split range
  • Valve position adjusting could be done without then use of any other instruments at the working place


Features :

  • Takes 4-20mA input signal as its power
  • Uses two wire lines
  • 4-20mA feedback module and limit switch module is optional
  • Signal drop voltage: 9.2 equal to load resistance 46017
  • 4-12mA and 12-20mA split range
  • Freely set alarm value and output status of limit switch
  • 32 letters LCD, clear showing
  • Pressure sensor with optional measuring diaphragm can run self-diagnoses
  • Self-diagnoses consists : pressure air stopped, valve locked, positioner failure, valve posited time, diaphragm or cylinder air leaking, packing abrasion and ventileinheit abrasion etc.
  • Adjustable sensitivity
  • Available to choose the output characteristics, such as linear, equal percentage, quick open and user defined
