Safety valve with a wrench -A48Y-16C overview: safety valve is a safety valve, its opening and closing parts under the action of external force in a normally closed state, when the device or the medium pressure inside the pipe increases, exceeds the set value automatically open, through the medium outside the system to prevent discharge piping or equipment in the medium pressure exceeds the set numerical. Safety valve is an automatic valve, mainly used in boilers, pressure vessels and pipes, the control pressure does not exceed the prescribed value, and plays an important role in the protection of personal safety and equipment operation. The safety valve (Aetvsafetyvalve) is automatically opened and closed according to the working pressure of the pressure system. It is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the setting pressure of the safety valve, the pressure is automatically opened to ensure that the medium pressure in the equipment and the pipeline is under the setting pressure, and the equipment and the pipeline can be protected to prevent accidents and reduce the loss
