Description
Midland 8–12" Butterfly Valve Stem Extensions
Midland 8–12" Butterfly Valve Stem Extensions provide a durable, factory-built solution for operating compatible butterfly valves installed in difficult-to-access locations.
Designed specifically for Midland 8–12" butterfly valves, these extensions help bring the operating point to a more accessible location when valves are installed below grade, beneath insulation, above ceilings, or in elevated piping systems. Available in multiple lengths, they eliminate the need for custom-fabricated operator shafts while maintaining reliable torque transfer and alignment.

Available Lengths
24" Extension
Provides a shorter remote operating distance for installations requiring moderate valve offset.
36" Extension
Suitable for installations requiring additional clearance from the valve body to the operating point.
48" Extension
Provides extended access for deeper, elevated, or insulated valve installations.
60" Extension
Designed for applications requiring a substantial increase in operating reach.
72" Extension
The longest listed option for installations requiring maximum operating distance from the valve.
Extension Configuration
Valve-Side Connection
The lower end of the extension mounts to the compatible Midland butterfly valve operator interface.
Rigid Steel Shaft
The extension shaft transfers operating torque while helping maintain proper alignment between the valve and remote operator.
Operator-Side Connection
The upper end provides the mounting point for the operating handle, gearbox, or compatible operator arrangement.
Construction Details
Each Midland butterfly valve stem extension uses a rigid welded steel shaft designed to transmit operating torque from the remote operator to the valve stem.
Heavy-duty mounting flanges help maintain alignment between the butterfly valve and the operating handle or gearbox, supporting smooth and dependable valve operation.
Factory-built construction reduces fabrication time in the field and provides a consistent extension assembly for compatible Midland butterfly valve installations.
Why Use a Valve Stem Extension?
Improved Accessibility
- Moves the operating point away from the valve body
- Useful for below-grade valves
- Useful beneath thick insulation
- Useful above ceilings or platforms
- Improves access for routine operation
Factory-Built Convenience
- Eliminates many custom fabrication requirements
- Preconfigured for compatible Midland valves
- Helps maintain shaft alignment
- Heavy-duty steel construction
- Multiple standard lengths available
Typical Applications
Below-Grade & Concealed Installations
- Buried valve installations
- Valve pits
- Insulated piping systems
- Above-ceiling valves
- Mechanical spaces with limited access
Commercial & Industrial Systems
- HVAC piping
- Water distribution systems
- Industrial process piping
- Mechanical room installations
- Elevated piping systems
Stem Extension vs. Direct Valve Operation
Stem Extension
A stem extension relocates the operating point away from the valve, allowing access when the valve body itself is difficult to reach.
Direct Operation
Direct operation places the handle or gearbox directly on the valve and is best suited for installations where the valve remains easily accessible.
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.

What valves are these extensions designed for?
The supplied product information identifies these extensions specifically for Midland 8–12" butterfly valves.
What lengths are available?
The supplied product information lists 24", 36", 48", 60", and 72" extension lengths.
What are the extensions made from?
The supplied product information identifies heavy-duty welded steel construction.
What is the purpose of a butterfly valve stem extension?
A stem extension allows a butterfly valve to be operated remotely when the valve itself is located below grade, behind insulation, above a ceiling, or in another difficult-to-access location.
Are the extensions factory assembled?
Yes. The supplied product information states that the extensions are factory assembled for proper alignment.
Can these extensions be used with any butterfly valve?
No. The supplied product information identifies compatibility specifically with Midland 8–12" butterfly valves.
Can the extension be used with a gearbox?
The supplied product information states that the extension is designed to maintain alignment between the butterfly valve and an operating handle or gearbox.
How do I choose the correct extension length?
Select the length that places the operator at the desired accessible location while maintaining proper alignment with the valve installation.
Why use a factory-built extension instead of fabricating one?
A factory-built extension provides a standardized assembly designed for compatible Midland valves and can reduce field fabrication time and alignment concerns.
What should I verify before ordering?
Confirm the butterfly valve size, valve series, mounting configuration, required extension length, operator type, and installation dimensions before ordering.
Important Ordering & Installation Notes
- This listing is for Midland 8–12" Butterfly Valve Stem Extensions.
- These extensions are intended for compatible Midland 8–12" butterfly valves only.
- Available lengths are 24", 36", 48", 60", and 72".
- Confirm the exact butterfly valve size and series before ordering.
- Verify the valve mounting configuration and operator interface.
- Select the extension length that provides the required operating height or offset.
- Confirm compatibility with the intended handle, gearbox, or operator arrangement.
