Product Description
The primary purpose of a safety valve is the protection of life, property, and the environment. Designed to open and relieve excess pressure from vessels or equipment, the safety valve then recloses to prevent further fluid release once normal conditions are restored. It serves as the last line of defense, ensuring that the system operates safely at all times.
A safety valve is not a process valve or pressure regulator and should not be misused as such. It is engineered to function solely for overpressure protection.
Basic Function of a Pressure Relief Valve

A pressure relief valve is a critical safety device, crucial for maintaining system integrity by:
- Relieving excess pressure
- Reclosing after restoring normal conditions
- Operating reliably under all circumstances
Pressure relief valves are essential in numerous industries, including chemical processing, oil and gas, power generation, and manufacturing. Their primary role is to prevent catastrophic failure by managing overpressure scenarios effectively. These valves ensure that your systems operate within safe limits, thereby protecting your investments and personnel.
