Wafer Type Swing Check Valve

Intervalve check valve models IVC and IVCT are single plate swing check valve, short pattern conforming to API 6D and ANSI B16.10 face to face dimensions. The valve has a simple but robust construction with total reliability. The low inertia disc design enables the valve to open or close at a very low differential pressure making it ideal for pump discharge duties etc. The short face to face dimensions and low weight can reduce the number of pipe supports. Either slip on or weld neck flanges are suitable for the range, the IVC model being supplied with internal gaskets. Gaskets are recommended for the IVCT model.

Conformity to codes and standards:

Design & face to face dimensions API 6D / ANSI B16.10
Valve testing API 598
Flange standard conformity: ANSI 150, DIN PN10 & PN16, BS 10 Table D & E
