Hydraulic control valve is a hydraulic control valve, hydraulic control valve is a main valve and attached to the catheter, pilot valve, needle valve, ball valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, Hydraulic electric control valve, pump control valve. Before the hydraulic control valve to be installed filters, and should facilitate the sewage requirements.

900X emergency shut-off valve is used for fire water and domestic water in parallel with the water supply system, used to deploy the water supply direction of the valve. When the fire broke out, the fire was in urgent need of a lot of water, immediately cut off the domestic water, to ensure adequate fire water; when the fire water pressure to stop reducing, the valve automatically opens, was normally open to resume living water supply. The valve so that the system does not require a separate fire special water supply pipe network, greatly reducing construction costs and water consumption. Valve control of high sensitivity, safe, reliable, easy commissioning, long service life.
 

900X emergency shut-off valve structural features and uses

Emergency shut-off valve for domestic water supply and fire water supply Parallel water supply system, the normal situation for domestic water, fire water when the fire occurs, the valve automatically turn off domestic water to ensure adequate fire fighting water. When the fire stopped reducing the pressure of water, the valve automatically restore domestic water, the valve eliminates the need for separate fire special water supply pipe network, which greatly saves construction costs and daily water consumption. The valve control sensitive, safe, reliable, simple commissioning, long service life.
