Modine 5H0806850000 Gas Valve

The Modine 5H0806850000 Gas Valve is the direct OEM replacement for 5H80685, engineered specifically for high-efficiency Modine gas-fired unit heaters and commercial heating systems. This 2-stage natural gas valve operates on a standard 24V AC control circuit and is pre-set for a 3.5" WC (water column) manifold pressure to ensure optimal combustion performance. Featuring a 1/2" NPT inlet and outlet, this 1/2 inch natural gas valve provides the precise flow regulation required for popular Modine models, including the PAE, PDP, and PTP series. As a veteran technician, you know that keeping Modine unit heater parts genuine is critical for maintaining equipment certification and safety. This 24V replacement gas valve is built for the rigors of industrial environments, offering reliable solenoid operation and consistent pressure regulation for natural gas HVAC systems.

• Direct OEM Compatibility: Seamlessly replaces discontinued part number 5H80685 without the need for manifold modifications.
• High-Precision Regulation: Factory-calibrated to 3.5" WC for stable flame characteristics and maximum heat exchanger efficiency.
• Standardized Logical Integration: Utilizing a 24V solenoid, this valve integrates directly with existing Modine ignition boards and Honeywell/White-Rodgers control systems.
• Dual-Stage Capability: Designed for 2-stage heating applications, allowing for improved temperature staging and reduced fuel consumption.

Is the 5H0806850000 compatible with propane (LP) units?
This specific model is calibrated for natural gas. If you are servicing an LP unit, a conversion kit or a dedicated LP valve must be utilized to match the higher manifold pressure requirements of liquid propane.

Can I use this to replace a single-stage gas valve?
While the 5H0806850000 is a 2-stage natural gas valve, it is primarily intended as a direct replacement for the 5H80685. Always verify the wiring harness and control board outputs to ensure the second stage solenoid is properly controlled.

What are the symptoms of a failing 5H0806850000 gas valve?
Common indicators include intermittent ignition failure, the unit "short cycling," or a significant drop in manifold pressure during the second stage of heating. Always check for 24V at the terminals before condemning the valve.
