Intervale check valve models IVC and IVCT are primarily single plate swing check valves with a short pattern wafer body conforming to the API6D and ASME B16.10 face-to-face dimensions. The valve has a simple but reliable and robust construction. The low inertia disc design enables the valve to open or close with a very low differential pressure which makes them ideal for services operating under low differential pressures.
The valve is ideal for pump discharge duties. The eccentrically mounted hinge pin 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 the IVC model due to the in-built face sealing ‘O’ rings provided on the sealing face. Gaskets are recommended while installing IVCT model valves.
