Valve Configuration
Lug-Style Body
Threaded body lugs allow each mating flange to be bolted independently for secure installation and easier servicing.
Stainless Steel Disc
The stainless steel disc rotates through the flow path to provide shutoff or intermediate positioning while offering corrosion resistance in compatible service.
Gear Operator
The enclosed manual gearbox multiplies handwheel input to provide smoother valve movement with reduced operating effort.
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 dependable sealing and smooth operation.
The enclosed gear operator provides increased mechanical advantage, making valve positioning easier and more controlled than direct lever operation where higher torque is required.
Why Choose a Gear-Operated Butterfly Valve?
Reduced Operating Effort
- Gear reduction multiplies handwheel torque
- Easier operation on larger valves
- Smooth controlled valve movement
- Reduced manual operating force
- Suitable for frequent isolation service
Precise Positioning
- Controlled disc movement
- Useful for gradual opening and closing
- Helps reduce abrupt flow changes
- Provides stable intermediate positioning
- Handwheel offers simple manual control
EPDM Seat
Resilient Sealing
The EPDM seat provides a flexible sealing surface around the stainless steel disc to support bubble-tight shutoff.
Typical Compatibility
EPDM is commonly used for water, HVAC, and many general-purpose industrial services. It is generally not suitable for petroleum oils or hydrocarbon-based fluids.
Stainless Steel Disc
Corrosion Resistance
The stainless steel disc provides strong corrosion resistance in many compatible water and industrial environments.
Durable Operation
The disc is designed for repeated opening and closing cycles while maintaining dependable performance within the valve's specified service conditions.
Lug-Style Body Design
Independent Flange Bolting
The lug body allows each flange side to be bolted independently, providing flexibility during installation and system maintenance.
End-of-Line Capability
Lug-style butterfly valves may support dead-end or end-of-line 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
Gear Handle vs. Lever Handle
Gear Handle
A gear operator provides greater mechanical advantage and slower, more controlled movement, making it useful where higher operating torque is required.
Lever Handle
A lever handle provides faster direct quarter-turn operation and is commonly used where operating torque is lower and rapid manual positioning is preferred.
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 end-of-line service where rated.
Wafer-Style Valve
A wafer valve is typically sandwiched between mating flanges using through-bolts and normally 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.
