A pressure safety valves or pressure relief valves is a safety device designed to protect a pressurized vessel or system during an over pressure event. An over pressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure (MAWP).
The primary purpose of a pressure safety valves or pressure relief valves is protection of life and property by venting fluid from an over pressurized vessel. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure safety valves may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that the design of the pressure safety valves be as simple as possible.

Spring Loaded Pressure Safety Valves
The basic spring loaded pressure safety valves or pressure relief valves has been developed to meet the need for a simple, reliable, system actuated device to provide over pressure protection. The Valve consists of a Valve inlet or nozzle mounted on the pressurized system, a disc held against the nozzle to prevent flow under normal system operating conditions, a spring to hold the disc closed, and a body/Bonnet to contain the operating elements. The spring load is adjustable to vary the pressure at which the Valve will open. When a pressure safety valves or pressure relief valves begins to lift, the spring force increases. Thus system pressure must increase if lift is to continue. For this reason pressure safety valves or pressure Relief Valves are allowed an over pressure allowance to reach full lift. This allowable over pressure is generally 10% for Valves on unfired systems. This margin is relatively small and some means must be provided to assist in the lift effort.
