Wafer Lugged Butterfly Valve Manufacturers in Mumbai
A reliable pipeline installation begins with the right valve construction. When secure flange mounting, compact design and quarter-turn operation matter, a wafer lugged butterfly valve is one option worth considering.
Ultra Valves Automation Pvt. Ltd. welcomes enquiries for wafer lugged butterfly valves from industrial buyers in Mumbai and across India. Explore construction materials, operation options, size ranges and technical specifications to identify the valve configuration your project needs.
Wafer Lugged Butterfly Valves for Industrial Piping
A wafer lugged butterfly valve is a quarter-turn valve with a lugged body construction. The lugs provide mounting points for securing the valve to compatible pipe flanges.
Unlike a conventional wafer body that is generally held between flanges using through-bolts, a lugged body uses a different bolting arrangement. The exact installation method depends on the valve design.
Buyers may encounter terms such as lugged type butterfly valve, wafer lug valve, lug type wafer butterfly valve or wafer and lugged butterfly valve when comparing industrial products.
The important consideration is the actual valve body construction, flange compatibility and operating requirements rather than the name alone.

Hydrostatic test pressures are not operating pressure ratings.
Lug and Wafer Type Butterfly Valve: What's the Difference?
Wafer and lugged butterfly valves both use a rotating disc for flow isolation, but their mounting arrangements are different.
| Feature | Wafer Type | Lugged Type |
|---|---|---|
| Body Construction | Compact wafer body | Body with mounting lugs |
| Installation | Generally held between flanges | Bolted through mounting lugs |
| Bolting Arrangement | Typically through-bolts | Model-specific lug bolts |
| Operation | Quarter-turn disc | Quarter-turn disc |
| End-of-Line Use | Requires design verification | Possible for specifically rated models |
| Selection | Based on piping arrangement | Based on piping and lug requirements |
A lugged body should not automatically be assumed suitable for end-of-line service. Confirm the manufacturer's rating and installation instructions.
Body, Disc, Seat and Shaft Material Options
The performance of a wafer lugged butterfly valve depends partly on the compatibility of its materials with the process medium.
The supplied specification lists cast iron, carbon steel, SG iron, SS304 and SS316 as body and disc options.
Seat materials include Nitrile, EPDM, Silicon, Viton, Hypalon, PFA and PTFE. Each material has different chemical and temperature characteristics.
Shaft options include AISI 410, AISI 304 and AISI 316. The final combination should be selected according to the application.
Material Selection Checklist
- Process fluid compatibility
- Operating temperature
- Operating pressure
- Required corrosion resistance
- Seat sealing requirements
- Body and disc material compatibility
- Shaft material selection
- Relevant project specifications
How Does a Lugged Type Butterfly Valve Work?
A lugged butterfly valve uses the same basic quarter-turn disc principle as other butterfly valve designs.
Open Position
The disc is positioned approximately parallel to the flow direction, allowing fluid to pass through the valve.
Disc Rotation
A lever, gearbox or actuator rotates the shaft and disc to change the flow passage.
Closed Position
The disc reaches the closed position and engages the seat to provide isolation, subject to the valve design.
