Pressure Safety Valve

ValvesOnly is reliable Pressure Safety Valve Manufacturers in USA. A pressure safety valve (PSV), sometimes referred to as a safety valve or a pressure relief valve (PRV), is an essential part of many industrial systems and procedures meant to safeguard workers and equipment against overpressure situations. A pressure safety valve’s main job is to automatically release excess pressure from a system in order to guard against potential harm to pipes, equipment, vessels, and other parts that could arise from pressure building that exceeds safe operating limits.

Working:
The Pressure Safety Valve Manufacturer in USA provides valve which works by releasing excess pressure from the system by enabling a controlled release of fluid (often gas or liquid) into the atmosphere or to a specified disposal place. By taking this step, the pressure is kept within safe ranges and catastrophic breakdowns that can cause explosions or other dangerous circumstances are avoided.

Difference between Pressure safety valve and Pressure relief valve:
A PRV opens gradually in relation to the pressure, while a PSV is open suddenly once the pressure hits a certain level in order to avoid over pressurization and a potential process safety incident. The function of both PSV and PRV is that they relieve the excess pressure from the system by opening automatically and they get closed automatically when the pressure in the system gets normal.
