Description

A lug-type butterfly valve with full PTFE coating, designed for corrosive and aggressive media including chemicals, acids, and alkalis. The body is ductile iron with a PTFE seat and a CF8 disc coated with PTFE or PFA. The lug configuration permits end-of-line service and removal without disturbing the adjacent pipeline.
