We feel pleasure to introduce ourselves as the foremost manufacturer and exporter of Electric Valve Positioner. It is manufactured using the premium grade components by our deft professionals. This is designed for integrated pneumatic control valves, particularly suitable for angle seat valves and diaphragm valves. It's an easy operate, rich software features product, operated via its LCD screen and keypad. Furthermore, this Electric Valve Positioner is thoroughly examined against variegated parameters by our quality inspectors before delivering to the esteemed patron's end.

Features:

  • Rugged construction
  • Optimum performance
  • Long working life

Valve positioner is designed for comparing the position of valve actuator and control signal to move the actuator accordingly. It can be used with linear valves as well as rotary valves. When diaphragm chamber's 0.2 to 1 bar pressure could not cope with friction and high differential pressures, valve positioners come in action. Apart from electric valve positioner, there are three other types, like pneumatic, electro-pneumatic, and digital valve positioners. The responsibility of this type is to send and receive electrical signals. It receives electric (usually 4-20 mA) signals. It uses electricity as an input signal.

Key points:

  • The buyers can select from a wide options by selecting movement, torque and other characteristics.
  • The three kinds of electric actuation are single-phase and three-phase alternating current (AC), and direct current (DC) voltage.
  • It is resistant to vibrations.
  • Low air consumption, easy feedback connection and convenient repair & maintenance are few features of this valve positioner.

Positioners will detecting the displacement sensor signal, for fast and accurate adjustment of valve position.
