The Powergenex Electro-Pneumatic Valve Positioner converts a 4–20mA input signal into a pneumatic output to operate single-acting or double-acting actuators. It comes in two models: EPL (linear type) and EPR (rotary type).

Its rugged aluminium housing has a corrosion-resistant coating and vibration-dampening design that provide reliability in harsh environments. It’s also designed with stainless steel pressure gauges for durability.

This easy to maintain positioner provides precise calibration through simple span and zero adjustments. It’s also available with ½ split ranges.
