The safety relief valve is specifically designed to open at the present pressure and then discharge fluid and till pressure reduces to acceptable levels.

The main purpose of a safety relief valve is the protection of property, life, and the environment.

Safety valves open very quickly and completely to avoid a disaster rather than controlling the pressure of a system. But a relief valve controls the pressure in a system and is opened in proportion as per the pressure increase in the system.

A safety relief valve is located in the tank from where it will receive air from the compressor.

Two types of safety valves exist and their diaphragm and piston type.

Safety valves are very commonly used on pressure cookers.
