Valve Configuration
Lug-Style Body
The ductile iron body uses threaded lug mounting points that allow the valve to be installed between compatible mating flanges.
Aluminum Bronze Disc
The corrosion-resistant disc rotates through the flow path to provide shutoff or intermediate flow positioning.
Lever Handle
The multi-position lever provides quick manual operation and allows the disc to be locked at selected positions for flow regulation.
Construction Details
The Midland lug-style butterfly valve uses a rugged ductile iron body with an epoxy coating to provide strength and enhanced corrosion resistance in demanding piping environments.
An aluminum bronze disc provides durable service and corrosion resistance, while the EPDM resilient seat supports dependable low-torque sealing.
The lever handle includes a multi-position locking mechanism that allows quick quarter-turn operation and controlled intermediate positioning.
Why Choose a Lug-Style Butterfly Valve?
Flexible Flanged Installation
- Lug-style body configuration
- Designed for ANSI Class 125/150 flanges
- Each flange side can be bolted independently
- Can support dead-end service where rated
- Compact installation footprint
Fast Manual Operation
- Lever handle operation
- Quick opening and closing
- Multi-position locking handle
- Supports intermediate disc positioning
- No gearbox required for listed sizes
Aluminum Bronze Disc
Corrosion Resistance
Aluminum bronze provides strong corrosion resistance in many compatible water and general industrial fluid environments.
Durable Operating Surface
The disc is designed to withstand repeated opening, closing, and positioning cycles while maintaining dependable performance.
EPDM Seat
Resilient Shutoff
The EPDM seat provides a flexible sealing surface around the disc to support bubble-tight bidirectional shutoff.
Typical Media Compatibility
EPDM is commonly suited for water, HVAC, and many general-purpose fluid applications, but compatibility should always be verified before installation.
Lever Handle Operation
Quick Quarter-Turn Control
The lever handle allows the butterfly disc to move rapidly between open and closed positions with approximately 90 degrees of handle travel.
Intermediate Positioning
The multi-position locking mechanism allows the operator to hold the valve at selected intermediate positions when flow regulation is required.
Typical Applications
Water & HVAC Systems
- Water distribution piping
- HVAC water loops
- Chilled water systems
- Heating water systems
- Building mechanical piping
Municipal & Industrial Systems
- Municipal water systems
- Industrial process piping
- Plant utility systems
- Equipment isolation
- Compatible general fluid service
Lever Handle vs. Gear Operator
Lever Handle
A lever handle provides fast manual operation and easy visual indication of disc position, making it well suited for smaller and medium-size butterfly valves.
Gear Operator
A gear operator provides greater mechanical advantage and slower, more controlled valve movement, which may be preferred on larger valves or higher-torque applications.
Lug-Style vs. Wafer Butterfly Valve
Lug-Style Valve
A lug-style valve uses threaded body lugs that allow each mating flange to be bolted independently and may support dead-end service where rated.
Wafer-Style Valve
A wafer-style valve is typically sandwiched between mating flanges using through-bolts and generally depends on both 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.
