Pressure Safety Valves & Safety Relief Valves – Uses, Selection Guide & Latest Prices
Pressure safety valves (PSVs) and safety relief valves (SRVs) play a crucial role in industrial safety by preventing excessive pressure buildup in boilers, hydraulic systems, pipelines, and processing plants. These valves automatically release excess pressure to protect equipment and ensure smooth operation.
As a leading manufacturer and supplier of safety valves in Delhi, Udhhyog provides high-quality pressure safety valves and safety relief valves designed for various industrial applications.
This guide covers the working principles, types, applications, selection criteria, and the latest price list to help you choose the right valve.
What is a Pressure Safety Valve (PSV) & Safety Relief Valve (SRV)?
A pressure safety valve (PSV) is a mechanical device that automatically opens when the system pressure exceeds a set limit, ensuring safety by releasing excess pressure.
A safety relief valve (SRV) operates similarly but provides gradual pressure release, reducing sudden pressure surges.
Working Principle of a Safety Valve
✔ The valve remains closed under normal pressure. ✔ When pressure rises beyond the safe limit, the valve opens automatically. ✔ Excess pressure is released, preventing system damage. ✔ The valve closes again when normal pressure is restored.
