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.
