BUTTERFLY VALVE PFA/PTFE Lined, Centric Bi-directional

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
