Pressure safety valve is the best overpressure protection devices for pressure-bearing equipment, pressure vessels and pressure pipelines. When the medium pressure rises above the set pressure, the safety valve automatically opens and then discharges the full amount to prevent the pressure from continuing to rise. When the pressure drops to the specified value, the safety valve automatically closes in time to ensure the safe operation of the equipment and pipelines.
