Butterfly Valves

Flangeless wafer-style butterfly valves for high-flow on/off and throttling service in water treatment, HVAC hydronics, chemical processing, and general industrial piping. Compact, lightweight, and economical compared to gate or ball valves at larger pipe sizes, butterfly valves seat between two flanges and deliver tight bubble-tight shutoff with a quarter-turn.

Our line spans 2" through 12" in four configurations:

  • Stainless disc, EPDM seat, gear operated — corrosion-resistant 316 stainless disc with a geared handwheel for controlled actuation on larger sizes.
  • Ductile iron disc, Buna-N seat, gear operated — the economical workhorse for water and neutral media.
  • Stainless disc, EPDM seat, lever operated — fast quarter-turn lever for 2"–10" lines.
  • Ductile iron disc, Buna-N seat, lever operated — lowest-cost lever option for general service.

EPDM seats suit water, dilute acids, and bases; Buna-N suits water, oil, and air. Choose a stainless disc for corrosive or higher-purity media.
