Maxitrol MR212D-1-88 1 Positive Pressure Modulating Regulator Valve

Product Description

The Maxitrol MR212D-1-88 is a one-inch positive pressure modulating regulator valve designed for heating applications. This valve adjusts outlet pressure based on the voltage received. Two springs enable the regulation of high and low fire settings. The minimum spring contacts the diaphragm assembly, while the maximum spring is positioned above the plunger. With no voltage, the weight of the plunger and spring exert downward pressure to set a regulated high fire. As voltage increases, the plunger rises, allowing the minimum spring to manage pressure for a low fire setting. A separate pressure regulator is not necessary for its operation.

• Voltage control adjusts outlet pressure.
• Spring-loaded design for regulating fire levels.
• Ideal for use with various systems including Series 14, Series 24, Series 44, Series 94, and Series SC10.
