What is a Pressure Relief Valve and How Does it Work?

A pressure relief valve is a direct-acting device, which means pressure acts directly upon the internal components of the valve. Pressure relief valves are normally closed, with internal components held in a position that creates a seal to prevent flow. When pressure increases beyond the valve''s specified limit, the valve is forced open ...

What is Pressure Relief Valve and How does it Work?

A pressure relief valve (PRV) or relief valve is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system.
