A pressure safety valve (PSV) is a type of safety valve used to protect a pressure vessel or system from overpressure. It works by automatically releasing excess pressure from the system to maintain safe and stable operating conditions. PSVs are commonly used in industrial and commercial applications such as oil and gas production, power generation, and chemical processing.

The key components of a PSV include a pressure sensor, a spring-loaded valve, and a discharge pipe. The pressure sensor detects any increase in pressure above the setpoint and activates the valve to release the excess pressure. The discharge pipe carries the released fluid to a safe location, away from any potential hazards.

There are several types of PSVs available, including conventional, bellows, and pilot-operated. The choice of a specific type of PSV will depend on the operating conditions and specific requirements of the system.

In addition to ensuring the safety of the system and its operators, PSVs also play an important role in maintaining system efficiency and reliability. By automatically releasing excess pressure, they prevent damage to equipment and reduce the risk of system failure.

A pressure safety valve (PSV) is a device used in the process and industrial plants to release excess pressure in a system, ensuring safety of equipment and personnel. The working principle of a PSV is based on the spring-loaded piston design. When the pressure in the system exceeds the set pressure, the increased force compresses the spring and opens the valve, allowing the excess pressure to escape through the outlet. As the pressure drops back below the set point, the spring returns to its original position, and the valve closes, maintaining the system pressure within safe limits.
