ZJ900X Emergency Shut-Off Valve

The ZJ900X emergency shut-off valve designed by Dazhong Valve Group, the hydraulic control valve is generally divided into two categories: diaphragm type and piston type, both of which work on the same principle. It is composed of a main valve and its external needle valve, pilot valve, conduit and pressure gauge, etc., and evolves into a remote-controlled float valve, pressure reducing valve, and slow-closing check valve according to the purpose, function and location of use. , flow control valve, pressure relief valve, hydraulic electric control valve, fixed water level valve, water pump control valve, differential pressure balance valve, emergency shutdown valve, etc.

• Hydraulic control valves are generally divided into two categories: diaphragm type and piston type, both of which work on the same principle.

• It is composed of a main valve and its external needle valve, pilot valve, conduit and pressure gauge, etc., which are combined with the purpose of use.

• Evolves into remote control float valve, pressure reducing valve, slow-closing check valve, flow control valve, pressure relief and pressure holding valve, hydraulic electric control valve, fixed water level valve, water pump control valve due to different functions and places. , differential pressure balance valve, emergency shut-off valve, etc.

• The valve can be installed vertically or horizontally in the pipeline.

• The hydraulic control valve is powered by the pressure difference between the upstream and downstream, and is controlled by the pilot valve, so that the diaphragm hydraulic differential operation is completely automatically adjusted by the hydraulic power, so that the main valve disc is completely opened or completely closed, or in the Adjust the status.

• Function and use: This valve is used in a water supply system in which fire water and domestic water are connected in parallel in living quarters.

• When firefighting uses water, the valve automatically closes in an emergency, cutting off the domestic water to ensure firefighting water. When the firefighting is over, the valve automatically opens to restore the domestic water supply. It can save costs compared to the traditional firefighting separate water supply.
