A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.

Relief valves are spring-loaded and characterized by gradual opening and closing. They are actuated by the upstream pressure and are suitable for incompressible fluids. Adjustable relief valves allow the pressure setting adjustment through the outlet port.
Pressure-relief valves limit the maximum pressure in a hydraulic circuit by providing an alternate path for fluid flow when the pressure reaches a preset level. All fixed-volume pump circuits require a relief valve to protect the system from excess pressure.
The relief valve diagram provides a detailed view of the different parts of the relief valve, including the inlet, outlet, valve disc, spring, and bonnet. It also shows the flow direction, pressure settings, and other important features of the valve.
