Midland Industries 9650EX4672 Butterfly Valve Stem Extension

Product Description

The MIDLAND INDUSTRIES 9650EX4672 is a butterfly valve stem extension designed to increase the distance between a butterfly valve operator and the valve body. Built from ductile iron with a black finish, this extension measures 72 inches in length and is rated for 4 to 6 inch nominal butterfly valves. It allows valve handles, gear operators, or actuators to be positioned at a more accessible location, which is especially useful in buried, submerged, or confined-space installations. This component is typically installed by licensed plumbers, pipefitters, or industrial mechanical contractors working on water, wastewater, HVAC, or process piping systems.

This stem extension is suited for use in both commercial and industrial piping applications where direct access to the valve operator is restricted or impractical. Typical scenarios include valve boxes, vaults, deep-set piping, and installations where the valve body is set below grade or behind a wall. It pairs with standard 4 to 6 inch butterfly valves where extended reach to the operator is required to meet accessibility or code requirements.

Key Features

• Ductile iron construction provides strength and resistance to mechanical stress in demanding piping environments
• 72 inch length accommodates deep-set or difficult-to-reach valve installations
• Rated for 4 to 6 inch nominal butterfly valves for broad fitment across common pipe sizes
• Black finish for corrosion resistance and standard industrial appearance
• Designed as a direct extension component, not requiring modification to the existing valve body

Compatibility

Suitable for use with 4 to 6 inch butterfly valves. Confirm operator drive connection type and stem square size before installation to ensure proper fit with the specific valve being serviced.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or mechanical contractor familiar with butterfly valve assemblies. Isolate the line and depressurize the system before disassembling any valve components. Verify that the stem extension drive connection is compatible with the existing valve stem before finalizing the installation. Follow applicable local mechanical codes and manufacturer torque guidance for all fastener connections.
