ZC500X Pressure Relief And Sustaining Valve

The ZC500X pressure relief and pressure holding valve designed by Dazhong Valve Group, the group 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., and evolves into a remote control float valve, pressure reducing valve, buffer valve, etc. Closed check valve, flow control valve, pressure relief and pressure holding valve, hydraulic electric control valve, fixed water level valve, water pump control valve, differential pressure balance valve, emergency shutdown valve, etc.

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

• Pressure relief valve: It can release the pressure in the water supply pipe that exceeds the safety setting value of the pilot valve, and maintain the pressure in the pipe below a safe setting value, so as to prevent high pressure or sudden pressure in the pipe from damaging the pipeline or equipment .It can be used for the pressure relief of the fire test circulation system of high-rise buildings to prevent the system from being dangerous due to excessive water pressure.

• Pressure sustaining valve: It can maintain the upstream water supply pressure of the main valve above a certain set value to ensure the pressure in the upstream water supply area of ​​the main valve. Emergency opening valve: Installed at the water outlet of the fire sprinkler pump, when the pump When the pressure at the water outlet rises above a certain set value, the valve opens immediately.
