Intervalve check valve models IVC and IVCT are primarily single plate swing check valve 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 make them ideal for services operating under low differential pressures.

The valve is ideal for pump discharge duties. The eccentric 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 IVC model due to the in-built face sealing 'O' rings provided on the sealing face. Gaskets are recommended while installing IVCT model valves.

The 3-piece design is available for various schedule pipes. This type of construction is of swing-out design and easy inline maintenance. By removing body bolts & nuts the complete valve may be lifted out of the line or swing-out by keeping one bolt. The valve can easily swing out of the line providing complete entry and fast disassembly or maintenance. The swing away feature also maintains pipe alignment during inline maintenance. The 3-piece design offers the function of both valve as well as a union. It can be used in screw pipe ends, socket weld pipe ends, butt weld ends, extended butt weld pipe ends. These ball valves can be easily used for automation by using pneumatic and electric actuators.

Features:-
