Single Lever Safety Valve

The single lever safety valve designed by Dazhong Valve Group is a safety valve of YOY Yongyi Valve Group Co., Ltd. The single lever safety valve is a safety device to prevent pressure equipment and containers from bursting or easily cause the pressure to rise or the internal pressure of the container exceeds the limit. It is a safety device widely used in pressure systems such as pressure vessels, boilers, and pressure pipes to ensure the safe operation of the pressure system.

GA42H single lever safety valve is suitable for power station boilers and pressure vessels with temperature ≤450℃, to prevent the pressure from exceeding the maximum allowable value, and the medium can be steam and air.
When the pressure of the container exceeds the design specification, the safety valve will automatically open, and the exhaust gas will reduce the excessive pressure in the device to prevent damage to the container or pipeline.
And when the pressure in the container drops to normal operating pressure, it automatically shuts down to avoid all the gas being exhausted due to the overpressure of the container, resulting in waste and production interruption.
The safety valve is mainly composed of three parts: the valve seat, the disc valve core and the loading mechanism.
Some valve seats are integrated with the valve body, and some are assembled with the valve body, which communicates with the equipment. The valve disc is often connected with a valve stem, which is tightly fastened to the valve seat. Loading mechanism, the size of the load can be adjusted.
