Applications

Wafer butterfly valves like the Nibco WD3010 are widely used in commercial and industrial piping systems for on/off and throttling control of water, mild chemicals, and other compatible fluids. The wafer design clamps between standard ANSI flanges, making it compact and easy to install in tight spaces. EPDM-seated valves are particularly common in HVAC chilled and hot water systems, potable water distribution, irrigation, fire protection, and light industrial process lines. The 250 PSI CWP rating and ductile iron construction make this valve suitable for higher-pressure service conditions where cast iron would be insufficient. The infinite-position lever lock allows the operator to hold the disc at any angle for precise flow regulation without a separate gear operator.
