Maxitrol MR510-3/4 3/4" Modulating Regulating Gas Valve

The Maxitrol MR510-3/4 is a 3/4" modulator-regulator valve that performs the dual functions of modulation and pressure regulation, designed specifically for atmospheric burner applications. This valve provides precise, non-fluctuating, instantaneous temperature control without requiring a motor or mechanically driven butterfly valve, making it ideal for applications requiring consistent temperature control.

Key Features:

• Dual-spring design to set high and low fire settings
• No separate pressure regulator required
• Suitable for natural, manufactured, mixed, liquefied petroleum, and liquefied petroleum gas-air mixtures
• 3/4" NPT threaded connections
• Pressure rating of 1/2 psi
• Low fire and high fire adjustments via spring settings

Operation:

With zero voltage applied, the minimum and maximum spring's down force, along with plunger weight, pushes down on the diaphragm thereby setting a regulated high fire. As voltage is applied, the plunger pulls up sufficiently until all plunger weight and maximum spring force is removed, with pressure now controlled by the minimum spring setting giving a regulated low fire condition.

Applications:

Ideal for problem-free stabilized area heating, elevated heating, consistent higher baking/drying temperatures, or other process applications requiring consistent temperature maintenance. Part of the Maxitrol Selectra Electronic Gas Flame Modulating System.
