Valve Configuration
Wafer-Style Body
The compact body is designed to fit between compatible mating flanges, helping minimize overall valve weight and installation space.
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.
Lever Handle
The locking lever provides fast quarter-turn operation and allows the valve to be held at selected intermediate positions for flow adjustment.
Construction Details
The Midland flangeless butterfly valve uses a durable cast iron body designed for dependable mechanical strength in commercial and industrial piping systems.
A corrosion-resistant stainless steel disc works against the resilient EPDM seat to provide smooth operation and dependable sealing.
The locking lever handle provides direct manual control without the need for a gearbox or external actuator, making the valve convenient for routine shutoff and compatible throttling applications.
Why Choose a Wafer-Style Butterfly Valve?
Compact Installation
- Thin wafer-style profile
- Fits between mating flanges
- Reduced installation length
- Lower overall weight
- Useful where piping space is limited
Simple In-Line Design
- No integral end flanges required
- Uses compatible mating flanges for installation
- Convenient for retrofit applications
- Simplifies many piping layouts
- Compact valve envelope
EPDM Seat
Resilient Sealing
The EPDM seat provides a flexible sealing surface around the stainless steel disc to support dependable shutoff performance.
Typical Compatibility
EPDM is commonly used for water, HVAC, and many general-purpose fluid applications but should always be verified for compatibility with the intended media.
Stainless Steel Disc
Corrosion Resistance
The stainless steel disc provides strong corrosion resistance for many compatible water and general industrial fluid applications.
Reliable Operation
The disc is designed for repeated opening, closing, and intermediate positioning within the valve's specified operating conditions.
Lever Handle Operation
Fast Quarter-Turn Control
- Quick open and close operation
- Direct manual control
- Simple visual indication of valve position
- No gearbox required
- Convenient for routine isolation
Multi-Position Locking
- Allows intermediate disc positioning
- Useful for controlled flow adjustment
- Locks handle securely in selected positions
- Simple field operation
- Supports both on/off and compatible throttling service
Typical Applications
Water & HVAC Systems
- Water distribution piping
- Chilled water systems
- Heating water systems
- HVAC mechanical systems
- Building utility piping
Industrial Systems
- Plant utility piping
- Industrial water service
- Equipment isolation
- Process support systems
- Compatible general fluid service
Wafer-Style vs. Lug-Style Butterfly Valve
Wafer-Style
A wafer-style valve is installed between mating flanges and is typically held in place by the flange bolting arrangement. Its compact profile helps reduce installation space and weight.
Lug-Style
A lug-style valve uses threaded mounting lugs around the body, allowing each flange side to be bolted independently and providing additional maintenance flexibility.
Lever Handle vs. Gear Operator
Lever Handle
A lever handle provides fast direct quarter-turn operation and is useful where valve torque can be comfortably controlled manually.
Gear Operator
A gear operator provides greater mechanical advantage and slower, more controlled movement where higher operating torque is required.
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.
