Festo GR-3/4 Pressure Relief Valve G 3/4, GR-3/4

Prevent injuries and equipment damage with this pressure relief valve from Festo. When fitted in a pneumatic system, it helps you to avoid a build-up of compressed air and reduces the risk of dangerous over-pressurisation. If the pressure of the airflow rises above a predefined safe level, the spring-loaded mechanism inside the device opens, bringing it back down again. Tightening or loosening its knurled screw lets you change the pressure needed to activate the relief function.
