Description
Electro-Pneumatic Proportional Pressure Regulator – EPV Series
High Precision Electronic Pressure Control for Industrial Automation
The EPV Series Electro-Pneumatic Proportional Pressure Regulator provides precise electronic control of compressed air pressure using analogue voltage or current input signals.
Designed for automated machinery, robotics, process control and industrial manufacturing, the EPV converts electrical control signals directly into proportional pneumatic output pressure, providing fast, accurate and repeatable pressure regulation without manual adjustment.
With integrated digital pressure display, pressure feedback outputs and multiple analogue input options, the EPV Series is ideal for closed-loop pneumatic control systems requiring accurate electronic pressure regulation.
Electronic Pressure Control
The EPV continuously regulates outlet pressure in proportion to the electrical input signal.
The internal electronic controller automatically adjusts the pneumatic pressure to match the required set point, providing smooth and highly repeatable pressure control for automated processes.
The front digital display allows pressure monitoring and simple configuration, while analogue and switching outputs provide pressure feedback to PLC, HMI and industrial control systems. The regulator also supports RS485 communication with customisable protocols.
