Regulating valve for drain systems

The Dayton 1MDA2 is a brass regulating valve designed for drain components. It handles a flow range of 3-5.5 GPM and measures 8 1/8 in overall height by 2 in overall length. The valve comes factory set with no test lever included.

Installers needing fixed flow control

This valve suits plumbers who need a pre-set regulating device for drainage lines within the stated GPM range. It is not for systems requiring adjustable pressure settings or a test lever for inspection. Buyers who need a different flow capacity should look at other models.

3-5.5 GPM flow range

The single specification that decides fit is the 3-5.5 GPM flow range. The brass body provides corrosion resistance for standard drain applications. Verify your system demands fall within this window before purchasing.

Questions about this item

How is the 1MDA2 regulating valve installed and what step is often missed?

Thread the brass body into the drain line using the 2-inch overall length as a guide, then verify the 3-5.5 GPM flow range matches the system demand before final tightening.

What maintenance will the 1MDA2 valve need over time?

Inspect the brass body and internal seat annually for mineral buildup or wear; clean or replace the seat if the 3-5.5 GPM regulation drifts outside the factory range.

What limit appears first on the 1MDA2 during sustained flow?

The 5.5 GPM upper regulation limit is reached first; flow beyond that point will not be controlled by the valve.
