Safety valve A42Y

The safety valve is a valve for safety protection. Its opening and closing parts are normally closed under the action of external forces. When the medium pressure in the equipment or pipeline rises, it will automatically open when it exceeds the specified value. The medium pressure in the pipeline or equipment will be prevented from exceeding the specified value by discharging the medium outside the system. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. According to the opening height of the safety valve disc, it can be divided into micro lift safety valve and full lift safety valve. The opening stroke height of the micro lift safety valve is: ≤ 0.05d0 (minimum discharge throat diameter); The opening height of full lift safety valve is ≤ 0.25d0 (minimum discharge throat diameter)
