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.

Design, Manufacturing and Testing Standards – Technology at a Glance

Kansei Wafer and Lug Centric Bi-directional butterfly valves are designed with few moving parts to provide a long service life with minimum maintenance. “A major advantage of Kansei product is an International compatibility.”

The Superior single piece through shaft design in One-piece body is a reliable and long-life solution for difficult conditions. Valves are with light weight and ideal economic solution for general purpose applications. Lugged valve gives alternative solution where flanged valves are considered and restrictions of space and cost. The Replaceable Seat design isolates the line media connection from body and stem. Replaceable seat design with inbuild molded O-ring eliminates the need for gaskets between the flanges and the valve. Also serve as the flange gasket to make valve more capable. Seat is convenient and economical for field replacement. Sealing is formed by preloaded contact between disc and seat. Shaft seal is suitable for pressure-vacuum service which is also self-adjustable, non-corrosive and heavy duty to absorb the thrust and extends valve cycle life. The Disc hub-edge profile is spherically machined and rounded manually with polishing to provide full concentric seating without obstruction to flow which gives maximum seat life, minimum torque and bubble tight shut-off. Disc-Screw connection with disc is positive, stronger and allows quick and easy disassembly.

Kansei PFA/PTFE Lined Centric Bi-directional Butterfly valves are designed to ensure a tight fit around the disc for bubble tight shut off in both direction and provide a constant torque with no maintenance. “A major advantage of Kansei product is an International compatibility.”

The Exceptional Design of one-piece thin disc stem lined with 3mm molded PFA providing high Kv value. The liner and disc are the only two valve parts in contact with the medium. Kansei improved design of disc leading to less deflection at higher pressure and tighter in line seal and for stem sealing system. Primary shaft sealing by preloaded contact between disc and liner hub and the secondary shaft seal by oversizing the shaft diameter in relation to the shaft hole in the liner. The liner and disc are molded and machined to close tolerances to provide low torque, less stress and deformation using opening and closing. PTFE atmospheric seat protects internal components from atmospheric corrosion and provides locating ring for actuator mounting. Fully encapsulated bottom shaft eliminates potential leak path at bottom of valve and eliminates the necessity for further sealing elements
