A Guide to Pressure Relief Valves

In pneumatics, a pressure relief valve (PRV) is essential to preserving the integrity and security of compressed air systems in pipelines and vessels. Alternatively referred to as a relief valve or pressure release valve, it serves as a safety measure to stop over pressurisation, which may cause harm or put workers and equipment at risk.

How Pressure Relief Valves Work:

By releasing excess pressure and preventing it from rising above pre-established levels, pressure relief valves are designed to safeguard compressed air systems. A spring-loaded mechanism that reacts to pressure applied to the valve seat powers the valve. The spring’s tension can be changed, usually by turning a control knob, to alter the opening pressure.

The valve opens to release excess pressure when pressure rises above the preset setting. This quick air release keeps the pressure from rising too high. In order to preserve system stability, the valve automatically closes when the pressure reaches the predefined level again.
