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.
