What is a Relief valve?

A relief valve is a type of valve that automatically releases pressure from a system when it exceeds a predetermined set point. This valve is critical for preventing overpressure, ensuring the safety of the system. Relief valves are commonly used in pressure systems involving hydraulic, pneumatic, steam, or gas applications. For example, in pressure tanks, piping systems, pumps, and air compressors, when the pressure exceeds a specified level, the valve opens to release excess pressure, preventing system damage or failure.

Application of Relief valve

✅ Hydraulic systems
Relief valves are used to prevent excess pressure in hydraulic machinery, preventing damage to equipment and pipes.
✅ Air compressors
In pneumatic systems, when pressure exceeds the set limit, the relief valve opens to release excess pressure.
✅ Steam boilers
In steam boilers, when overpressure occurs, relief valves automatically open to keep the boiler safe.
