There are two types of lug-type butterfly valves: pressure through holes and threaded holes.

1. The installation method of lug adjustment for butterfly through-type pressure hole is the

same as that of clamped butterfly adjustment. Their stability is not as good as flange type;

2.The installation method of lug valves with threaded holes is different from that of wafer type and flange type.

The pressure hole of lug type butterfly valve is equivalent to a bolt. When connecting to the pipe flange,

the bolt method plate is penetrated and tightened directly. The pressure hole of the lug-type butterfly valve is sufficient,

and the bolts at the flange end are tightened with bolts. This kind of installation method is even more stable than the flange butterfly valve.

Our Full Lug Type Butterfly Valve is designed for reliable shut-off and flow control in industrial water distribution systems, municipal pipelines, HVAC projects, water treatment plants, and general utility services. Manufactured from high-quality ductile iron, the valve combines excellent mechanical strength with long service life while maintaining cost efficiency for large-scale projects.

The valve body adopts a full lug type design, allowing installation at the end of a pipeline without requiring downstream flanges. This structure simplifies maintenance and makes valve replacement easier while ensuring secure pipeline connections. Compared with standard wafer butterfly valves, the lug configuration provides greater installation flexibility for various piping systems.

This PN16 butterfly valve is suitable for medium-pressure applications and complies with international flange standards. Precision machining ensures accurate alignment between the valve body, disc, and stem, delivering smooth operation and reliable sealing performance. The resilient seat effectively minimizes leakage and reduces operating torque, making the valve suitable for manual lever, gearbox, pneumatic actuator, or electric actuator operation.

Our ductile iron lug butterfly valve is available with different disc materials, including ductile iron, stainless steel, and aluminum bronze, together with EPDM, NBR, or other seat materials to meet different water quality and operating conditions. Multiple coating options such as fusion bonded epoxy provide enhanced corrosion resistance for long-term outdoor or underground service.

As an experienced butterfly valve manufacturer, we offer flexible production solutions for OEM and ODM projects. Valve sizes range from DN50 to DN600, with additional sizes available upon request. Every valve undergoes pressure testing, sealing inspection, and dimensional verification before shipment to ensure consistent quality and dependable field performance.

This water butterfly valve is widely used in clean water systems, irrigation networks, fire protection installations, cooling water circulation, pumping stations, and municipal infrastructure projects. The compact structure reduces installation space while minimizing maintenance costs throughout the service life.

We provide complete technical support, competitive factory pricing, and fast delivery for global distributors, engineering contractors, wholesalers, and project buyers. Customized branding, marking, packaging, and actuator assembly services are also available to support your business requirements.

If you are looking for a dependable Full Lug Type Butterfly Valve, Lug Type Wafer Butterfly Valve, Ductile Iron Lug Butterfly Valve, or PN16 Water Butterfly Valve, our manufacturing capabilities and strict quality control ensure products that meet international performance standards while delivering outstanding value for industrial applications.
