Center Disc Butterfly Valve

Flow-Tek The valve was developed to provide reliable sealing in water and air lines, and is today the industry benchmark.

The most striking feature of Aqua seal Butterfly Valve is its integrally-molded body liner. FLOWTEK's elastomer body seat is vulcanized insitu onto the body using high temperature and pressure, and this provides longer life and superior performance when compared to valves with loose liners.

Aquaseal requires no maintenance, and is truly a fit-and-forget valve.
