Design, Manufacturing and Testing Standards – Technology at a Glance

Kansei EPDM and PTFE Centric Bi-directional Butterfly valves are designed to ensure a bubble tight shut off in both direction and provide a Maximum flow area.
“A major advantage of Kansei product is an International compatibility.”

The Exclusive Design of two-piece body with one-piece wafer-thin disc stem provide the very less obstruction to flow. Body locating holes provide easy placing and perfect centering of the valve between the flanges.

Rounded & Buffed disc edge gives full concentric sealing with lower torque, which gives longer seat life.

Kansei designed Primary stem sealing accomplished by a preinstalled contact between seat surface and rounded disc hub area which overtake the pressure rating of valve and prevents the leakage through the stem area to atmosphere.

An inbuild ‘O’ ring on the seat surface provide flange sealing and eliminates the need for additional flange gasket.

The seat is completely field replaceable and isolated from line media which allows superior performance of valve with extended service life. The seat design in such a way to ensure seal drop-tight and bi-directional at low to high pressure range.

Split body for easy maintenance.

This product is not recommended for dead end services.

This type of valve can be installed in vertical or horizontal pipeline and any intermediate orientation.
