Maxitrol MR251D-1 1/2 Modulating Gas Pressure Regulator Valve HVAC Control Valves & Actuators - 1/2

The Maxitrol MR251D-1 1/2 is a modulating gas pressure regulator valve designed for commercial and industrial gas control applications. This precision-engineered regulator provides accurate downstream pressure control for natural gas and LP gas systems.

Key Features:

• 1-1/2 inch NPT connection size for high-capacity gas flow
• Modulating design allows for proportional pressure control based on input signal
• Durable cast aluminum body construction for long service life
• Internal relief valve for overpressure protection
• Compatible with natural gas and propane (LP) applications
• Suitable for use in heating systems, boilers, and industrial burner applications

The MR251D series regulators are known for their reliability and precision in maintaining consistent gas pressure, making them ideal for applications requiring responsive modulation and accurate pressure regulation. The 1-1/2 inch port size provides excellent flow capacity for larger commercial equipment.
