Flow control valve for plumbing systems

The Dayton 1MDA4 regulating valve manages water flow from zero to twelve gallons per minute in drain and trap installations. Brass body construction provides corrosion resistance for continuous service in commercial and residential plumbing.

Installers needing adjustable flow regulation

This valve suits plumbers and facility engineers who require precise flow control within the stated range. It is not for systems that demand factory-preset pressure settings or applications requiring a test lever for routine inspection.

Adjustable range up to twelve gallons per minute

The zero-to-twelve GPM span is the key specification that determines whether this valve matches the design flow of the circuit. Verify the required flow rate before specifying this component.

Questions about this item

How is the 1MDA4 regulating valve installed and what step do people get wrong?

Thread the brass body into the drain line using the 3 1/4 in overall length as a guide; the step often missed is confirming flow direction before tightening.

What maintenance or replacement will the 1MDA4 regulating valve need later?

Inspect the brass body and internal seat for mineral build-up or wear; replace the valve if regulation across the 0-12 GPM range becomes inconsistent.

What limit shows up first on the 1MDA4 regulating valve under sustained use?

The 12 GPM maximum flow rating is the first limit reached; sustained operation at that rate can accelerate seat erosion and reduce regulating accuracy.
