Wafer vs. Lugged Butterfly Valve: What’s the Difference?
One of the most common questions buyers ask is the difference between a wafer butterfly valve and a lugged butterfly valve. While both serve similar purposes, they differ in design and application.
Comparison: Wafer Butterfly Valve vs. Lugged Butterfly Valve
| Feature | Wafer Butterfly Valve | Lugged Butterfly Valve |
|---|---|---|
| Design | Held in place by flange bolts. No threading. | Threaded lugs for secure flange connections. |
| Isolation Capability | Cannot isolate one side of the pipeline. | Can isolate one side for maintenance. |
| Durability | Lightweight but less durable. | Heavier and more robust construction. |
| Applications | Suitable for low-pressure systems. | Ideal for high-pressure, high-maintenance systems. |
When it comes to features such as flexibility, durability and ease of maintenance then without doubt the lugged butterfly valve is the preferred option for industries.
It is therefore important to put into consideration the requirements of the system before choosing between wafer and lugged butterfly valves. The lugged design is most suitable for maintenance-heavy applications As it is probably known, the configuration of the BB90 adapts to high-stress conditions most efficiently. – RUFSUPPLY
Different Types of Lugged Butterfly Valve
A lugged butterfly valve is a type of valve with threaded inserts (lugs) on the body, allowing it to be bolted directly between flanges. It provides a secure connection and can be used for end-of-line service or in systems requiring frequent disassembly.

What Is a Lugged Butterfly Valve?
A lugged butterfly valve is a type of quarter turn valve that utilizes a round disk in order to regulate the flow of fluids. The name “lugged” is used to portray the threaded projections (lugs) on the body of the valve which provides the opportunity to fix the valve directly to the flanges of the pipes. This design helps in dissecting one part of the piping system for essential maintenance without interfering with the other part.
Applications of Lugged Butterfly Valves:
- Water treatment plants
- Chemical processing industries
- HVAC systems
- Oil and gas pipelines
- Food and beverage production
- Power generation facilities
They are employed in various applications because the valve is miniature in size, has fewer losses when in operation, and the tests show that it is easy to maintain.
Lugged butterfly valves are defined accurately as the mainstays of the present day flow control systems, since they are at the same time effective and dependable. – Industry Expert

Lugged butterfly valve is widely used in the systems which need the frequently maintenance as well as isolaion ,such as industrial legpipe, drinking water pipeline distribution,chemical exporting and importing pipeline etc. Threaded lugs of theirs make possible sections of the pipeline to be isolated without shutting off the entire systems.
When choosing a lugged butterfly valve, Picking out information corresponding with operating pressure, temperature, medium form, and material match. For corrosive conditions, stainless steel or PTFE lined variants are the best options. Also, confirm that the valve is the correct size as well as the pressure rating required for your pipeline.
The lugged butterfly valve is designed from materials that tends to be strong against corrosion, like stainless steel, and duplex steel, as well as by epoxy coating. These valves are suitable for seawater, aggressive chemicals or full humid environments.
- The flanges and the pipeline should also be clean and well aligned.
- When tightening the bolts, there is a lattice like structure to be followed because every valve body has some particular tendencies as to the way it will be stressed.
- Ensure that the valve is properly oriented with respect to its operational status of either open or closed arrangement during the installation so as not to cause damage when in use.
- Pressure again with low pressure after its installation to check for any leakage results.
A lugged butterfly valve has threaded end pieces which enable one part of the pipeline to be shut down while the other is open. This feature makes it possible for them to be used for systems that may need some periodical or partial attendance.
- Tighten Bolts: The problem of leakage can also be checked by inspecting the seals and tightening bolts properly. Replace damaged gaskets if necessary.
- Stiff Operation: Search for roughness on the body of the stem or deposits such as rust on the stem, and if any, clean the same or lubricate if necessary.
- Misalignment: In this case, the valve should be reinserted so that it fits well with the flanges.
- Flow Issues: Check that the valve is fully open or closed depending on the need or as per the application needed.
