Description

A lug-type butterfly valve with a ductile iron disc and EPDM seat, intended for on-off isolation service in water supply, wastewater, HVAC, and general industrial pipeline systems. The lug body design supports end-of-line service. A gear operator is fitted to enable controlled manual operation at medium and large diameters where operating torque reduction is required.
