Midland Wafer-Style Flangeless Butterfly Valve w/ Buna-N Seat & Lever Handle

Midland Industries flangeless butterfly valves provide dependable shutoff and flow control for commercial, industrial, water, HVAC, and general service piping systems. The rugged ductile iron body is paired with a ductile iron disc and resilient Buna-N seat for reliable sealing and long service life.

These wafer-style valves install between ANSI Class 125/150 flanges and feature a locking lever handle for quick quarter-turn operation. Sizes are available from 2 through 12 inches.

Construction Details

The valve body is manufactured from durable ductile iron for excellent strength and impact resistance. A precision-machined ductile iron disc provides reliable throttling performance while the Buna-N elastomer seat delivers dependable sealing.

A heavy-duty locking lever allows the disc position to be adjusted and secured for accurate flow regulation or full shutoff.

The compact wafer design minimizes installation space while reducing overall valve weight compared to lug-style alternatives.

Important Notes

Designed for installation between ANSI Class 125/150 flanges.

Verify media compatibility with Buna-N seat material before installation.

Follow manufacturer installation, torque, and maintenance recommendations for optimum service life.
