Flow regulation range

The Dayton 1MDA1 regulating valve controls water flow between 2 and 3 gallons per minute. Its brass body resists corrosion in plumbing installations. The valve measures 7 1/2 inches in overall height and 2 inches in overall length. No test lever is included with this component.

Suitable applications and limits

This valve suits residential and light commercial plumbing systems requiring fixed flow regulation within the 2-3 GPM range. It is not intended for high-pressure hydronic heating circuits or processes needing adjustable set points. Installers who require a test lever for manual operation should select a different model.

Critical selection specification

The factory-set flow range of 2-3 GPM is the single specification that determines whether this valve matches the system design. Verify the required flow rate before purchase because the setting cannot be altered in the field.

Questions about this item

How much heat does the brass body add to a plumbing system running continuously?

The brass body conducts heat from the fluid inside but adds no measurable heat of its own; temperature rise depends on the water temperature and flow rate.

What pipe fittings or adapters are needed to install the 2-inch long valve?

The valve has standard threaded ends; you need matching NPT fittings or adapters for your pipe size and thread type.

Will the 7-1/2-inch overall height fit alongside older 1/2-inch copper supply lines?

The 7-1/2-inch height is independent of pipe diameter; check the vertical clearance at your installation point to confirm fit.
