Pressure Relief Valve
Definition - What does Pressure Relief Valve mean?
As the name suggests, a pressure relief valve is a special type of equipment whose purpose is to release the pressure from the well or from any pressure vessel if its pressure has been exceeded from the rated pressure parameters. Generally, such type of valve have an auxiliary passage through which the pressurized fluid can pass through whenever high pressure is developed in a restricted confinement.
Petropedia explains Pressure Relief Valve
The primary purpose of pressure relief valves is to keep a particular equipment free from forces applied on its internal boundaries developed because of increased operating pressure due to abnormal working conditions. These pressure relief valves finds its applications in all mechanical and chemical manufacturing organizations such as oil refineries, petrochemical plants, fertilizers, automotive sector, etc. These valves automatically gets activated whenever the pressure builds up in a system more than its pressure rated capacity and diverts some amount of fluid through an auxiliary passage so as to provide a relief in a system pressure.
