Midco International 841970 Gas Valve
The Midco International 841970 Gas Valve is a 24V commercial-grade component engineered for high-demand applications in boilers, industrial furnaces, and commercial HVAC systems. This 24V 3.5"WC gas valve provides precise pressure regulation, pre-set to a 3.5" Water Column (WC) manifold pressure, making it ideal for natural gas configurations or propane conversions where accurate fuel-to-air ratios are critical. This slow-opening gas valve is designed to reduce ignition noise and mechanical stress during start-up cycles, ensuring a smooth transition into high-fire mode.
As a veteran HVAC technician knows, managing gas flow control in space-constrained units requires a compact yet rugged design. The Midco 841970 features a durable body intended for continuous operation in harsh boiler room environments. With a flow capacity of up to 100 CFM, this replacement gas valve is compatible with various Midco burner assemblies and high-efficiency heating equipment. Integrating this gas control valve ensures your system maintains its 3.5 inch WC pressure rating for optimal combustion efficiency and safe operation across all industrial heating apps.
Key Benefits- Precise Pressure Regulation: Factory-set to 3.5" WC to ensure consistent manifold pressure for natural gas furnaces and commercial boilers.
- Slow-Opening Action: Engineered to provide a controlled start, preventing "hard" ignitions and extending the life of the burner assembly.
- Broad Compatibility: Rated for use with natural gas, propane, and other compatible media in industrial HVAC environments.
- Compact Footprint: Optimized for easy installation in tight furnace cabinets where standard 3.5-inch diameter valves may be difficult to fit.
- 24V Coil System: Standard 24V power requirements allow for seamless integration with existing HVAC control boards and ignition modules.
How do I verify if the 24V 841970 coil has failed?
Using a multimeter set to Ohms, measure the resistance across the two leads. A significiantly lower or open loop (OL) reading typically indicates a shorted or failed coil that will prevent the valve from opening during the call for heat.
Can I use this 841970 Midco valve for propane (LP) applications?
Yes, while factory-configured for natural gas at 3.5" WC, this valve is compatible with propane systems. However, a technician must perform a manifold pressure adjustment to reach the standard 10" WC required for LP gas.
What are the signs of a sticking gas valve?
If you confirm 24V at the valve terminals but have zero outlet pressure at the manifold port, the valve is likely stuck closed. Conversely, if gas flows when the valve is de-energized, the internal seat may be fouled with debris.
