EPP4 Proportional Air Pressure Regulators - Basic Series

Brand: Parker Hannifin

The EPP4 family is an electro pneumatic pressure regulator. The BASIC range precision is based on a reliable design: a pulsed width modulated solenoid valve controls the output pressure proportionally to an Analog input signal.

EPP4 electro pneumatic pressure regulator range with integrated electronic system provides highest accuracy thanks to a high precision closed loop signal. 

The regulator is also designed to achieve the best reliability thanks to a piston concept.
