IVSCV Check Valve

Cast Steel Swing Check Valve

The IVSCV range of check valves offers optimum solution for back flow prevention in liquid and gas lines. Our special design feature provides a rugged construction, reliable operation and long service life. The valve finds applications in various segments of the process industries covering chemical, petrochemicals, pharma, steel, alumina,  power plants and common utilities.

The design offers a low pressure drop operation, which makes the valve more energy efficient. Pressure sealed bonnet design is incorporated for high pressure applications for reliable sealing. Valve can be provided with a external dashpot arrangement to provide non-slam operation, ideal to prevent water hammer.
