Lug Butterfly Valves

BI-TORQ butterfly valves in the lug style are designed for reliable flow control, featuring a circular disc mounted on a rotating shaft that opens or closes with a simple quarter turn. The valve gets its name from the disc’s wing-like shape and movement, which resembles the motion of a butterfly. Explore our variety of fully lugged butterfly valves below.

Lug Butterfly Valves Key Features

• ISO mounting pad is a true ISO pad that allows for direct mounting of gears, pneumatic and electric actuators, and a 10-position manual handle.
• Stem bushing reduces torque and isolates the stem from the valve body.
• Shaft Seal is an EPDM O-ring that creates a bubble-tight design while limiting contact areas between the body and shaft.
• A standard 316 stainless steel disc is included on all models; aluminum bronze and cast iron discs are also available upon request.
• Cast iron body is epoxy-coated for a durable, attractive finish. A fully encapsulated body ensures the valve body never comes into contact with the fluid.
• The square shaft allows mounting to ISO-standard pneumatic and electric actuators as well as gear operators.
• The standard 316 stainless steel shaft never contacts the media, and the one-piece design ensures positive disc positioning.
• Available in EPDM, BUNA-N, Viton®, and PTFE, the seat face guarantees a perfect seal with flanges without additional joints or gaskets.
