Description

A lug-type butterfly valve with a ductile iron disc and EPDM seat, designed for on-off isolation in water supply, wastewater, HVAC, and general industrial pipeline systems. The lug body allows secure bolting to the pipeline and supports end-of-line service. Manual handle operation enables straightforward valve control for small to medium pipe sizes.
