Lug type butterfly valve

The lug butterfly valve features integrated lug-type threaded bosses on the valve body, enabling bolted connection with pipeline flanges without full through-bolts. Different from wafer-type valves, its lug structure allows secure installation and reliable sealing on both pipeline ends, supporting single-sided flange mounting and end-of-line service.
Adopting premium elastic soft sealing and precision-machined disc surface, it delivers consistent zero-leakage shutoff and smooth flow regulation. Durable, versatile and easy to maintain, this valve is a highly dependable solution for diverse municipal water pipeline systems.

Secure Reliability for Your Piping System

When your piping layout requires maximum structural stability, easy maintenance, and the flexibility to isolate sections of your line, our Lug Butterfly Valve is the ideal professional choice. Designed with integrated, threaded metal lugs, this valve bolts directly to the flanges on both sides, offering a heavy-duty, highly secure installation.

Engineered for End-of-Line Service & Easy Maintenance

The standout feature of the lug-style design is its independent bolting system. Unlike wafer valves that share through-bolts between flanges, the lug butterfly valve is secured to each flange with separate bolts.

This smart engineering allows you to safely disconnect and perform maintenance on one side of the pipeline while the other side remains under full pressure (known as end-of-line service or single-sided mounting).

It keeps your system running with minimal downtime.
