Kelly Pneumatics, Inc. introduces an Electronic Pressure Relief Valve for high flow applications.

Perfect for applications that need to sustain a consistent chamber pressure, this valve varies relief flow rates automatically, subject to dynamic increases in chamber pressure. Unlike traditional mechanical relief valves, the Electronic Relief Valve provides variable relief pressure based on a control signal.
