POSITIONER

Pneumatic and electro-pneumatic positioners are commonly used to control flow, pressure, temperature, or level via an air actuated valve.

The positioner interprets an analog signal (air or electric) and directs compressed air to the air chambers of the pneumatic actuator. The result is a corresponding adjustment to the degree of openness on the valve being operated by that actuator.

Pneumatic positioners commonly receive a 3-15 PSI air input signal whereas electro-pneumatic positioners employ integral I/P transducers for converting a 4-20 mA electrical input signal to a 3-15 PSI air output signal. Positioner housings are NEMA 4 or 4X construction with a stainless steel gauge set as standard in both types of positioners.
