Overview

The Lug Concentric Butterfly Valve is a quarter-turn butterfly valve that uses a rotating disc to provide reliable on/off isolation and smooth flow throttling within a compact, lightweight body. It is offered across a size range of 1/4“ to 2”. The body is built from a351 cf8m / a216 wcb for durability in service. A Delrin / Peek seat delivers tight, bubble-tight shut-off, while the a182 f316 disc balances strength with corrosion resistance. With its lug body configuration and lever, gear, electric, pneumatic actuation, it suits demanding pipeline service where space and weight are at a premium.
