If the pressure exceeds a defined threshold the valve activates and automatically releases pressure. Typically used for gas or vapor service boiler safety valves pop fully open once a pressure threshold is reached and remain open until the boiler pressure reaches a pre-defined safe lower pressure.

The main function of a safety valve is to relieve pressure. It is located on the boiler steam drum and will automatically open when the pressure of the inlet side of the valve increases past the preset pressure. All boilers are required by ASME code to have at least one safety valve dependent upon the maximum flow capacity (MFC) of the boiler. Safety ValveThis device is typically used for steam or vapor service. It operates automatically with a full-opening pop action and recloses when the pressure drops to a value consistent with the blowdown requirements prescribed by the applicable governing code or standard.
