900X Emergency shut-off valve
Product overview
Hydraulic control valve is the valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached pipe, pilot valve, needle valve, ball valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc. Hydraulic control valve should be installed before the filter, and should be convenient for sewage requirements.
900X emergency shut-off valve is a kind of valve used to adjust the direction of water supply in the parallel water supply system of fire water and domestic water. In case of fire, a large amount of water is urgently needed for fire control, and the domestic water shall be cut off immediately to ensure sufficient water for fire fighting; when the pressure of water for fire fighting is stopped and the water pressure is reduced, the valve will automatically open and be in normal open state to restore the domestic water supply. There is no need to set up a separate water supply system and water supply valve, so that the water supply system can be saved greatly. The valve has high control sensitivity, safety and reliability, simple debugging and long service life.
Product details
