Cowinns one-piece wafer or lug soft seal butterfly valves were designed with extended neck and concentric disc and seat configuration. One-piece designed valve stem was mechanically retained
in the body neck and no part shall be exposed to the line media. Valve seat was encapsulate d with body totally ,it will ensure body isolated from the line media, and no flange gaskets were required.

Design features:
Simple and compact construction, quick 90° on-off operation
Small size and light weight
Easy installation and maintenance
Minimized operating torque, energy saving
Bubbles tight sealing with no leakage under the pressure testing
Long service life ,standing the test of tens of thousands opening/closing operations.
Flow curve tending to straight line, excellent regulation performance.

Products range 
Size:1 1/2''~48''
Rating: ANSI 150LB
Main Body materials: Carbon Steel, Cast Iron, Stainless steel, C95800,C95400,C95500.
Operation: Lever, Gear, Pneumatic, Electric operator.
