Ductile iron silent check valve

DN50-300
Product OverviewLift check valve, the valve disc slides vertically up and down along the axis of the valve seat, and the positive flow of the medium lifts the valve disc to conduct; When reversing, the valve disc falls and presses the valve seat to stop. The structure is similar to the stop valve, with strong sealing performance. It is mostly used for medium and small caliber high-pressure pipelines, and it is installed at multiple levels.Technical parameters• Nominal diameter: DN15 to DN250• Nominal pressure: PN16-PN100; Class150～Class600Valve body material: WCB, A105 forged steel, 304, 316LSealing material: Fluororubber PTFE、 Sitaili alloy• Operating temperature: -29 ℃ to 425 ℃• Connection method: flange, internal thread, socket weldingApplicable media: water, oil, steam, compressed air, acid-base mediaExecution standards: GB/T12235, API602Product advantages1. High sealing accuracy, better sealing performance when closed than when rotated, and excellent zero leakage performance2. The valve core has stable guiding positioning, anti vibration, and is suitable for high-pressure and pulsating pipelines3. Compact structure, few parts, low failure rate, suitable for continuous and stable working conditions4. The forged steel version can meet the working conditions of high pressure, high temperature, flammable and explosive media5. Can be paired with spring assisted closure to reduce water hammer impact6. Compact size, suitable for pump outlet and equipment front-end protectionApplicable scenariosChemical high-pressure pipelines, hydraulic oil pipelines, boiler feedwater, pump outlets, air compressors, fine chemicals, pharmaceutical pipelines
