Butterfly Valve

Butterfly valves service high performance and fire protection systems and are available in a broad size range with wafer lug, grooved, or press end connections. Butterfly valves provide bi-directional dead-end service in commercial and industrial service and can provide many maintenance-free cycles and still accommodate “bubble tight” shut off.
