Safety Valve


LJV safety valve is the best orverpressure protection device taking care of pressure equipment,containers and pipelines.When the medium pressure rises over the allowed pressure,the safety valve will automatically open and fully discharge to protect the equipment from pressure going on rising and will automatically close when the pressure lowers to the setting pressure to ensure the equipment and pipeline to run safety.

The bonnet of a sealed safety valve is enclosed to prevent dust and external matters from invading and meanwhile protect toxic combustible media from overflowing.The open safety valves is mainly used for the pipelines and containers with the steam medium to reduce the spring chamber’s temperature as its bonnet is open,while the safety valve with a radiator is suitable for the medium with a temperature over 350C ~570C.The spring safety valve with a lever can be opened manually by the lever when the media pressure over 75% of setting pressure(on the premise of ensuring safety).
