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.
