Description

A lug-type butterfly valve with PTFE coating, designed for aggressive chemical, high-purity, and corrosive media applications. Available in cast iron, ductile iron, carbon steel, and stainless steel body materials with a range of elastomeric and PTFE seat options. Operates via 90° rotation with an eccentric structure to reduce seal friction.
