Description

A wafer-type butterfly valve actuated by a worm gear mechanism, designed for installation between flanges in space-constrained pipeline applications. The disc is aluminium bronze for corrosion resistance in water, seawater, and mildly corrosive media; the seat is EPDM for elastic sealing. Available in sizes DN50 - DN1200 with multiple body and seat material options.
