Industrial Valves (Butterfly, Wafer, Ultraflo) - 330

Butterfly valves are available with different end configurations, actuator styles, disc materials & resilient seat elastomers - as determined by the specific application. They can be found across many industries including industrial processing, water, wastewater, dry bulk conveying, paper mills, light slurry handling, food and beverage, HVAC, transportation, and others. For quick reference we've listed some of our more common styles & materials below. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. Their handles incorporate a notch plate which allows you to position the disc incrementally in order to throttle the flow (usually about 8-10 positions). Wafer & Lug-style butterfly valves are designed to be used with ANSI Class 125/150 flanges pipe flanges. Wafer style fits between the flanges and are held in place by the force of the mating flanges, while Lug style are bolted directly to the mating flange(s). Grooved end & Tri-clamp butterfly valves are also available.
