Safety Valves

In order to protect the systems that are designed according to different fluids and a certain pressure against all the adversities, the valves that provide controlled discharge of the fluid (steam, liquid, gas) when the design pressure rises above a certain value are called safety valve.

Within the safety rules for pressure vessels, the pressure vessel is usually equipped with 2 safety valves.

Duty of Safety Valve

It releases a certain amount of steam, gas or liquid if the system pressure rises above the valve's set pressure. In this way, it protects the desired pressure system against unauthorized pressure increases.The safety valve reaches its full discharge capacity with a maximum pressure increase of 10% of the set pressure. Shut-off pressure of the safety valve: It is maximum 10% for compressible materials and less than 20% for incompressible substances.
