Industrial Lug Butterfly Valve Supplier
A lug butterfly valve is a quarter-turn valve designed with threaded lug inserts around the body, allowing it to be bolted directly between two pipe flanges. Compared with wafer type butterfly valves, lug butterfly valves are especially suitable for end-of-line service, because one side of the pipeline can be removed without disturbing the other side.
As a professional lug butterfly valve manufacturer, Wenzhou Zoncic Machinery Technology Co., Ltd supplies industrial lug style butterfly valves in ductile iron, carbon steel, stainless steel, and other materials according to different pressure ratings, disc materials, and seat options. Our products are widely used in water treatment, HVAC, chemical, and general industrial applications where compact design and service convenience are required.
- ✔ Lug body design suitable for end-of-line service
- ✔ Easy installation and removal from one side of pipeline
- ✔ Available in ductile iron, carbon steel, and stainless steel
- ✔ Suitable for water treatment, HVAC, chemical, and industrial systems
