Valve Configuration
Lug-Style Body
Threaded body lugs allow each mating flange to be bolted independently, supporting secure installation and easier service access.
Stainless Steel Disc
The stainless steel disc rotates through the flow path to provide shutoff or intermediate positioning with corrosion resistance in compatible service.
Lever Handle
The manual lever provides fast quarter-turn operation and locks at multiple positions for controlled flow adjustment.
Construction Details
The Midland lug-style butterfly valve uses a heavy-duty ductile iron body designed for strength and dependable service in demanding piping systems.
A corrosion-resistant stainless steel disc works against the resilient EPDM seat to provide reliable sealing and smooth operation.
The manual locking lever handle provides direct quarter-turn control and can be secured at multiple positions to support both shutoff and flow regulation.
Why Choose a Lever-Operated Butterfly Valve?
Fast Manual Operation
- Quarter-turn opening and closing
- Direct manual control
- Simple visual position indication
- No gearbox required
- Convenient for routine isolation service
Multi-Position Flow Control
- Multiple locking positions
- Supports intermediate disc positioning
- Useful for controlled flow adjustment
- Secure handle positioning
- Simple field operation
EPDM Seat
Resilient Sealing
The EPDM seat provides a flexible sealing surface around the stainless steel disc to support dependable bubble-tight shutoff.
Typical Compatibility
EPDM is commonly suited for water, HVAC, and many general industrial services, but is generally not recommended for petroleum oils or hydrocarbon-based fluids.
Stainless Steel Disc
Corrosion Resistance
The stainless steel disc provides strong corrosion resistance for many compatible water and industrial fluid applications.
Durable Operation
The disc is designed for repeated opening, closing, and intermediate positioning within the valve's specified service conditions.
Lug-Style Body Design
Independent Flange Bolting
The lug-style body allows each flange side to be bolted independently, providing flexibility during installation and maintenance.
Dead-End Service
Lug-style butterfly valves may support end-of-line or dead-end service when permitted by the manufacturer's specific pressure ratings and application requirements.
Typical Applications
Water & HVAC Systems
- Water distribution piping
- Chilled water systems
- Heating water systems
- HVAC mechanical systems
- Building utility piping
Municipal & Industrial Systems
- Municipal water systems
- Plant utility piping
- Industrial water service
- Equipment isolation
- Compatible general fluid service
Lever Handle vs. Gear Operator
Lever Handle
A lever handle provides fast direct quarter-turn operation and convenient multi-position flow adjustment where operating torque is manageable.
Gear Operator
A gear operator provides greater mechanical advantage and slower, more controlled valve movement where higher operating torque is required.
Lug-Style vs. Wafer Butterfly Valve
Lug-Style Valve
A lug-style valve uses threaded body lugs that allow each 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.
