Parallel safety reflux valve

Product features

Suitable for installation on the liquid phase reflux pipeline at the outlet of the tank pump in liquefied petroleum gas stations. When the pressure in front of the pump exceeds the specified value, the valve automatically opens and plays a safe reflux role, ensuring the safe operation of equipment and pipelines.

It is an automatic pressure relief protection device that is opened by imported static pressure. It is one of the important safety accessories for pressure vessels. Its function is to automatically open the valve and quickly discharge a certain amount of medium by relying on the pressure of the medium itself when the pressure inside the vessel exceeds a certain value. When the pressure inside the container drops to the allowable value, the valve automatically closes, keeping the pressure inside the container below the upper limit of the allowable pressure, automatically preventing accidents that may occur due to overpressure.

So safety valves are also known as the final protection devices of pressure vessels. Safety valves can automatically open and close according to working pressure, and are generally installed on equipment or pipelines in closed systems to protect system safety.
