EPR - Proportional control valves

Download technical datasheet

Proportional control valves allow the output pressure to be adjusted by means of an electrical signal. Depending on the measured pressure, there is an electrical output signal, called "feedback signal". These valves have a display that shows the regulated pressure, but also facilitates configuration through the easily accessible user display. The EPR series is available in G1/8", G1/4" and G1/2" sizes.
