High-Performance Lug Type Butterfly Valves by FlowBiz – Dead-End Isolation & Flow Control
When process lines require piping disconnects, downstream maintenance, or dead-end isolation without depressurizing the upstream system, FlowBiz Lug Type Butterfly Valves provide the ideal engineering solution. Unlike wafer-style valves, lug valves feature threaded bolt holes along the outer body collar that bolt directly into companion pipe flanges from both sides.
Featuring a heavy-duty powder-coated body, high-strength disc, and resilient liner, FlowBiz lug-type butterfly valves allow for independent piping removal on either side of the valve. Operated via an ergonomic multi-position lever handle with a locking trigger, they deliver bi-directional bubble-tight sealing for industrial water, chemical, and process lines.
