ntervalve check valve models IVC and IVCT are primarily single plate swing check valve with a short pattern wafer body conforming to the API 6D and ANSI B16.10 face to face dimensions. The valve has a simple but robust construction with reliability. The low inertia disc design enables the valve to open or close with a very low differential pressure which make them ideal for services operating under low differential pressures.

 

The pressure drop across the valve in fully open condition is relatively low and makes them ideal for pump discharge duties. The eccentric disc shaft in combination with the disc seat guarantees a positive shut off of the returning media.

 

The short face to face dimensions and low weight allows a simple space saving installation between the mating companion flanges. The valves are suitable for mounting between weld neck or slip on type companion flanges of different standards. The need for flange gaskets during installation is totally eliminated in the case of IVC model due to the in-built face sealing 'O' rings provided on the sealing face. Gaskets are recommended while installing IVCT model valves.
