Valve Configuration
Lug-Style Body
The ductile iron body uses threaded lug mounting points that allow the valve to be installed between compatible flanges.
Aluminum Bronze Disc
The corrosion-resistant disc rotates through the flow path to provide shutoff or intermediate flow positioning.
Gear Operator
The enclosed manual gear operator provides controlled valve positioning and reduces the operating effort required on larger valve sizes.
Construction Details
The Midland lug-style butterfly valve uses a heavy-duty ductile iron body designed for strength and durability in demanding piping applications.
An aluminum bronze disc provides enhanced corrosion resistance, while the EPDM resilient seat provides dependable sealing performance in compatible water and fluid service.
The enclosed gear operator provides smooth mechanical advantage for controlled opening, closing, and intermediate valve positioning.
Why Choose a Lug-Style Butterfly Valve?
Flexible Flanged Installation
- Lug-style body configuration
- Designed for ANSI Class 125/150 flanges
- Can support dead-end service where permitted
- Suitable for bidirectional flow
- Compact compared with many full-body valve designs
Controlled Operation
- Manual gear operator
- Provides mechanical advantage
- Allows smooth valve positioning
- Useful for larger valve sizes
- Suitable for shutoff and throttling applications
Aluminum Bronze Disc
Corrosion Resistance
Aluminum bronze offers strong resistance to corrosion in many compatible water and industrial fluid environments.
Durable Flow Control Surface
The disc provides a durable rotating closure element for repeated valve opening, closing, and flow-positioning cycles.
EPDM Seat
Resilient Sealing
The EPDM seat provides a flexible sealing surface designed to support dependable shutoff around the butterfly disc.
Compatible Water Service
EPDM is commonly used in compatible water applications, but media and temperature suitability should always be verified before installation.
Gear Operator Benefits
Reduced Operating Effort
The gearbox provides mechanical advantage, reducing the force required to rotate the butterfly valve disc.
Controlled Positioning
Gear operation allows gradual valve movement, making it useful where controlled positioning or throttling is required.
Typical Applications
Water & Municipal Systems
- Water distribution piping
- Municipal utility systems
- Building water systems
- HVAC water loops
- General water service
Commercial & Industrial Systems
- Industrial process piping
- Mechanical rooms
- Plant utility systems
- Equipment isolation
- Compatible fluid control applications
Lug-Style vs. Wafer Butterfly Valve
Lug-Style Valve
A lug-style butterfly valve uses threaded mounting lugs around the body, allowing each adjoining flange to be bolted independently and potentially supporting dead-end service where rated.
Wafer-Style Valve
A wafer butterfly valve is typically sandwiched between flanges using through-bolts and generally relies on both mating flanges for installation support.
Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.
