Groove type bottom valve (suction bottom valve)

DN50-200
Product OverviewThe bottom valve belongs to the one-way check valve and is installed at the bottom of the water pump suction pipe, submerged below the liquid level. When pumping forward, the valve disc opens and the medium flows into the pipeline; When the water pump stops, the valve disc automatically closes, locking the water in the pipeline to prevent backflow and ensuring that there is always water stored in the pump, realizing that the water pump can be started without needing to fill the pump every time; The top is equipped with a stainless steel filter screen to prevent water grass, sand, gravel, and debris from entering the pipeline and protect the water pump impeller. This is a groove (clamp) connection style commonly used in fire protection and water supply and drainage pump rooms.##Technical parameters-Nominal diameter: DN50, DN65, DN80, DN100, DN125, DN150, DN200-Nominal pressure: PN16 (1.6MPa)-Valve body material: ductile iron-Filter material: 304 stainless steel punched mesh-Sealing element: NBR nitrile rubber/EPDM ternary ethylene propylene-Connection form: groove clamp connection-Applicable media: clear water, fire water, clean sewage-Operating temperature: 0-80 ℃-Execution standards: GB/T 13927, GB 5135 Fire related specifications-Installation method: Underwater vertical installation at the end of the suction pipe##Product advantages1. * * Check water retention, no need to repeatedly fill the pump * *: automatic sealing and water locking during shutdown, no backflow in the pipeline, no need to manually add water during secondary startup, improving the operation and maintenance efficiency of the pump room.2. * * Comes with a built-in filter and pre filtration * *: The stainless steel porous filter intercepts sediment, weeds, and gravel to prevent impurities from damaging the pump impeller and extend the pump's lifespan.3. * * Groove connection, quick disassembly * *: The clamp groove structure allows for faster on-site installation, disassembly, and maintenance compared to flange bottom valves, reducing construction costs.4. * * Sensitive opening and closing, moderate flow resistance * *: The valve disc opens easily, and the water pump absorbs water smoothly; Fast closing response, good sealing effect, and small leakage.5. * * Cast iron valve body is sturdy and durable * *: coated with electrostatic spray red paint for corrosion and rust prevention, resistant to water immersion, suitable for long-term underwater immersion conditions.6. * * Easy maintenance * *: The filter screen can be disassembled and cleaned separately, and the sealing gasket can be replaced separately without the need to remove the valve as a whole.##Applicable scenariosAt the end of the suction pipes for fire water tanks, water supply and drainage pumps, circulating water pumps, deep well water pumps, irrigation pumps, etc.

    The bottom valve belongs to the one-way check valve and is installed at the bottom of the water pump suction pipe, submerged below the liquid level. When pumping forward, the valve disc opens and the medium flows into the pipeline; When the water pump stops, the valve disc automatically closes, locking the water in the pipeline to prevent backflow and ensuring that there is always water stored in the pump, realizing that the water pump can be started without needing to fill the pump every time; The top is equipped with a stainless steel filter screen to prevent water grass, sand, gravel, and debris from entering the pipeline and protect the water pump impeller. This is a groove (clamp) connection style commonly used in fire protection and water supply and drainage pump rooms.
    Technical parameters
    -Nominal diameter: DN50, DN65, DN80, DN100, DN125, DN150, DN200
    -Nominal pressure: PN16 (1.6MPa)
    -Valve body material: ductile iron
    -Filter material: 304 stainless steel punched mesh
    -Sealing element: NBR nitrile rubber/EPDM ternary ethylene propylene
    -Connection form: groove clamp connection
    -Applicable media: clear water, fire water, clean sewage
    -Operating temperature: 0-80 ℃
    -Execution standards: GB/T 13927, GB 5135 Fire related specifications
    -Installation method: Underwater vertical installation at the end of the suction pipe
    Product advantages
    1.Check water retention, no need to repeatedly fill the pump * *: automatic sealing and water locking during shutdown, no backflow in the pipeline, no need to manually add water during secondary startup, improving the operation and maintenance efficiency of the pump room.
    2. Comes with a built-in filter and pre filtration * *: The stainless steel porous filter intercepts sediment, weeds, and gravel to prevent impurities from damaging the pump impeller and extend the pump's lifespan.
    3.  Groove connection, quick disassembly * *: The clamp groove structure allows for faster on-site installation, disassembly, and maintenance compared to flange bottom valves, reducing construction costs.
    4.  Sensitive opening and closing, moderate flow resistance * *: The valve disc opens easily, and the water pump absorbs water smoothly; Fast closing response, good sealing effect, and small leakage.
    5. Cast iron valve body is sturdy and durable * *: coated with electrostatic spray red paint for corrosion and rust prevention, resistant to water immersion, suitable for long-term underwater immersion conditions.
    6.  Easy maintenance : The filter screen can be disassembled and cleaned separately, and the sealing gasket can be replaced separately without the need to remove the valve as a whole.
    Applicable scenarios
    At the end of the suction pipes for fire water tanks, water supply and drainage pumps, circulating water pumps, deep well water pumps, irrigation pumps, etc.
