Maxitrol M651W-1 Valve

The Maxitrol M651W-1 is a high-performance modulating gas valve engineered for atmospheric burners requiring higher outlet pressures. Featuring 1" NPT connections, this unit is rated for a maximum 1/2 PSI inlet pressure and provides a precise low fire adjustment range of 1.2" to 2.5" w.c. Designed for seamless integration into industrial and commercial heating systems, it utilizes covered wire terminals to ensure secure electrical connections in demanding environments. This direct acting valve responds to a DC control signal, allowing for infinitely variable burner input and superior thermal efficiency. Technicians favor the M651W-1 series for its reliable Selectra modular gas modulation capabilities, ensuring stable performance during part-load operations. It serves as a drop-in replacement for specified HVAC modulation controls, maintaining consistent pressure regulation without the hunting common in lower-grade components.

• Precise Modulation: Provides accurate control over gas flow for optimal combustion across the entire firing range.
• Increased Outlet Capability: Specifically designed for atmospheric burner systems that demand higher outlet pressures.
• Durable Construction: Built with high-grade materials to withstand continuous cycling in commercial boiler and furnace applications.
• Streamlined Installation: Features 1" NPT threading and protected terminals to reduce field labor time.
• Reliable Pressure Regulation: Maintains a stable 1/2 PSI max inlet pressure threshold for consistent burner operation.

What is the primary application for the M651W-1?
This valve is utilized in atmospheric burner setups where standard modulation valves cannot provide the necessary higher outlet pressure for specific manifold requirements.

Can the low fire setting be field adjusted?
Yes, the low fire adjustment range (1.2" to 2.5" w.c.) allows technicians to calibrate the minimum input to meet OEM specifications for the appliance.

What type of signal is required for modulation?
The Maxitrol M651W-1 typically operates on a low-voltage DC signal provided by a compatible Selectra electronic control system.
