Gully water control valve

DN50-300
F8741X groove pressure reducing and stabilizing valve belongs to diaphragm type hydraulic self-control pressure reducing valve. It relies on a guide valve to sense the outlet pressure, pure hydraulic drive, automatic pressure stabilization, and the valve body is connected by groove clamps. It is a commonly used pressure reducing and stabilizing valve in fire water supply systems.Core ParametersCaliber: DN50 to DN300• Nominal pressure: PN10, PN16Applicable media: clear water, fire water• Medium temperature: 0-80 ℃Valve body material: QT450 ductile iron, red epoxy anti-corrosion coatingDiaphragm seal: EPDM rubber• Connection method: groove (clamp) connection• Supporting components: pressure regulating valve, needle type regulating valve, front and rear pressure gauges, control copper tube, maintenance ball valveExecution standard: GB/T13927Usage scenariosFire sprinkler, fire hydrant pipe network pressure reduction and stabilization, vertical zoning water supply for high-rise building fire protection, pump room pressure stabilization pipeline, domestic water supply high-pressure branch pressure reduction, park fire water supply system, used for pipelines with high upstream water pressure that need to stabilize downstream outlet pressure.Product advantages1. Self stabilizing, no need for power supply, relying on automatic adjustment of water pressure. When the inlet pressure and flow fluctuate, the outlet pressure remains stable;2. Equipped with dual pressure gauges, real-time visualization of inlet and outlet pressures, and convenient on-site pressure adjustment;3. Groove clamp connection, faster than flange installation speed, suitable for rapid construction of fire pipes;4. The pressure reduction range can be adjusted, and the target outlet pressure can be easily set through the top guide valve, balancing dynamic and static pressure stability;5. Slow closing suppresses water hammer, reduces pressure shock in the pipeline network, protects fire pipes, nozzles, and alarm valve groups;6. Convenient maintenance, with external pilot valves and control pipelines, and no need to disassemble the main valve body for debugging and replacing accessories;7. The flow channel is unobstructed, with low resistance and sufficient water supply flow, meeting the high flow water demand for firefighting.

  • F8741X groove pressure reducing and stabilizing valve belongs to diaphragm type hydraulic self-control pressure reducing valve. It relies on a guide valve to sense the outlet pressure, pure hydraulic drive, automatic pressure stabilization, and the valve body is connected by groove clamps. It is a commonly used pressure reducing and stabilizing valve in fire water supply systems.

    Core Parameters

    Caliber: DN50 to DN300

    • Nominal pressure: PN10, PN16

    Applicable media: clear water, fire water

    • Medium temperature: 0-80 ℃

    Valve body material: QT450 ductile iron, red epoxy anti-corrosion coating

    Diaphragm seal: EPDM rubber

    • Connection method: groove (clamp) connection

    • Supporting components: pressure regulating valve, needle type regulating valve, front and rear pressure gauges, control copper tube, maintenance ball valve

    Execution standard: GB/T13927

    Usage scenarios

    Fire sprinkler, fire hydrant pipe network pressure reduction and stabilization, vertical zoning water supply for high-rise building fire protection, pump room pressure stabilization pipeline, domestic water supply high-pressure branch pressure reduction, park fire water supply system, used for pipelines with high upstream water pressure that need to stabilize downstream outlet pressure.
