Kev Tiv Thaiv Hluav Taws Xob Hluav Taws Xob Valve Deluge Alarm Valve
During the operation of the water supply system, when the water pressure is less than the set pressure relief value, the spring elasticity of the pilot valve is greater than the water thrust, and the pilot valve disc is closed. When the water pressure exceeds the set value, the pilot valve opens and the diaphragm chamber starts pressure relief to achieve the function of pressure relief and pressure regulation.
