Valvesonly is a Pressure safety valve manufacturer in USA. The pressure safety valve is one of the most important automatic safety mechanisms in a pressure system. During an over-pressure occurrence in a pressurised vessel or machinery, the primary role of a pressure safety valve is to safeguard people, property, and the environment. When the pressure in a vessel or system exceeds the design pressure or maximum permitted operating pressure, it is called an over-pressure case. A pressure safety valve opens to alleviate excess pressure in vessels or equipment before closing to prevent additional fluid escape until normal operating conditions are restored. The pressure safety valve must function properly at all times and in all conditions.
What is pressure relief valve and pressure safety valve?
Pressure relief devices on a vessel or machinery are usually referred to as "Pressure Safety Valve" or "Pressure Relief Valve." These words vary in the following aspect, despite the fact that they are often used interchangeably:
Pressure safety Valve:
A relief device on a compressible fluid or gas filled tank is referred to as a pressure protection valve. The opening of such a valve is abrupt. When the valve's fixed pressure is reached, the valve almost fully opens.
Pressure relief valve
The word "pressure relief valve" refers to a relief device on a liquid-filled vessel. The opening of such a valve is proportional to the rise in vessel pressure. As a result, if the pressure is progressively raised, the valve does not open abruptly.
