Honeywell V4944N1011 Gas Valve

The Honeywell V4944N1011 Gas Valve is a heavy-duty, two-stage pressure regulating gas valve designed for precision fuel control in high-demand commercial heating systems. Engineered as a direct replacement for V4844N1186, this 1-inch NPT valve is built with a rugged die-cast aluminum body to withstand rigorous field conditions. It operates on 120Vac line voltage and is specifically rated for natural gas applications, supporting a robust 300-1000 CFH capacity. This solenoid-operated diaphragm valve combines safety shutoff and pressure regulation into a single unit, making it ideal for atmospheric boilers, commercial water heaters, and rooftop heaters. With a fast 6-second maximum opening time and a critical 2-second maximum closing time, it ensures responsive performance and reliable final shutoff service. The unit features slow opening characteristics to prevent hard starts and includes dual 5/16" UNF bleed tappings and a 1/8" pilot tapping for versatile installation configurations.

Key Benefits:

• Dual-Stage Precision: Reliable Honeywell V4944N1011 performance with adjustable high-fire (3"-4.5" WC) and low-fire (0.8"-2" WC) setpoints for optimized combustion.
• Broad Compatibility: Seamlessly replaces legacy V4844 and V8844 gas valves in commercial and industrial HVACR setups.
• Extreme Durability: Rated for a wide operating temperature range of -40°F to 150°F, ensuring stability in unconditioned mechanical rooms.
• Safety Integrated: Solenoid-operated diaphragm gas valve design provides 0.5 PSI pressure rating and failsafe closing upon power loss.
• Simplified Wiring: Equipped with 1/4" spade terminals and three 30" lead wires for efficient field integration with dual-stage controllers.

Common Questions:

Can this valve be used with LP gas?
No, the Honeywell V4944N1011 is designed specifically for natural gas. For Liquid Petroleum applications, an LP-specific model like the V4944L must be used.

What is the proper mounting orientation for this valve?
This valve requires upright horizontal mounting for the internal diaphragm and regulator components to function according to factory specifications.

Is this a direct replacement for the V4844N1186?
Yes, the V4944N1011 is the official direct replacement for the V4844N1186, maintaining the same 1" pipe size and 120V electrical requirements.
