You buy equipment to get the job done.It should never be the reason you can’t.

Guaranteed Up-Time

No other service provider promises this. They make money when your equipment breaks. We keep your equipment working so you can too.

Major Cost Savings

Top-quality planned maintenance means repair, rental, and replacement costs go down. When your forklifts are efficient, so is your warehouse.

A Safer Warehouse

Unserviced forklifts can cause costly inventory damage, but staff are more likely to be injured using a forklift that’s not working properly too, causing a massive expense.

High-performance lug butterfly valve for water treatment applications

What is a Lug Butterfly Valve?

A lug butterfly valve is a quarter-turn valve with threaded lug holes that allow it to be bolted directly to each pipe flange. This design enables end-of-line service and simplifies pipeline maintenance while providing reliable flow isolation and control.

What is the difference between a Lug Butterfly Valve and a Wafer Butterfly Valve?

A lug butterfly valve uses threaded lug holes for independent flange connection, allowing one side of the pipeline to be removed without affecting the other. A wafer butterfly valve is installed between flanges using through bolts and is typically used for general pipeline service

What are Lug Butterfly Valves used for?

Lug butterfly valves are widely used in water treatment, municipal water supply, HVAC, fire protection, chemical processing, marine, mining, and industrial pipeline systems where reliable shut-off and easy maintenance are required.

Can a Lug Butterfly Valve be used for end-of-line service?

Yes. The threaded lug body design allows one side of the pipeline to be disconnected while the opposite side remains pressurized, making lug butterfly valves ideal for end-of-line applications.

What pressure ratings are available?

Laux lug butterfly valves are available in PN10, PN16, ANSI Class 125, and ANSI Class 150, with other pressure ratings available upon request.

What seat materials are available?

Common seat materials include EPDM, NBR, H-EPDM, FKM (Viton®), PTFE, Silicone, and Hypalon (CSM). The recommended material depends on the operating media and temperature.

What body materials are available?

We offer Ductile Iron (DI), Carbon Steel (WCB), CF8 (SS304), CF8M (SS316), and Aluminum Bronze body materials to suit different operating environments.

Can Lug Butterfly Valves be automated?

Yes. Lug butterfly valves can be supplied with manual lever, gearbox, pneumatic actuators, or electric actuators for automated flow control.

What international standards do your Lug Butterfly Valves comply with?

Our valves are manufactured in accordance with EN 593, API 609, ISO 5211, API 598, EN 12266, and other international standards depending on project requirements.

What sizes are available?

Standard sizes range from DN50 to DN1200 (2"–48"), with additional sizes available for OEM projects.

How do I select the correct material for my application?

Material selection depends on the fluid type, operating temperature, pressure, corrosion level, and installation environment. Our engineering team can recommend the most suitable body, disc, shaft, and seat material combination.

How are Lug Butterfly Valves tested before delivery?

Every valve undergoes hydrostatic shell testing, seat leakage testing, operational torque inspection, dimensional verification, and visual quality inspection before shipment.

What industries commonly use Lug Butterfly Valves?

Typical industries include water treatment, wastewater, municipal infrastructure, HVAC, fire protection, chemical processing, marine, mining, oil & gas, and power generation.

Do you provide OEM and customized Lug Butterfly Valves?

Yes. Laux Valve offers comprehensive OEM and ODM services, including customized dimensions, materials, coatings, pressure ratings, branding, packaging, and actuator configurations.

Why choose Laux Valve as your Lug Butterfly Valve manufacturer?
