Laars Heating Systems RV2001900 Gas Valve
The Laars Heating Systems RV2001900 Gas Valve is a heavy-duty, direct-replacement component engineered for high-performance gas-fired boilers and commercial water heaters. This 24V natural gas valve is designed to operate with a precise 4" WC manifold pressure, ensuring stable combustion and reliable modulation across demanding duty cycles. Featuring a 3/4" NPT inlet and outlet, it provides the necessary flow capacity for large-scale heating equipment, including compatibility with the Laars MiniTherm JVI/JVH-225N and Mighty-Stack TL series. As a critical control for hot surface ignition (HSI) systems, this Laars replacement gas valve maintains rigorous safety standards by regulating appliance fuel delivery with professional-grade accuracy. Whether you are performing a mid-season repair or a system-wide overhaul, this Laars RV2001900 assembly ensures the pressure regulation remains within manufacturer specifications to prevent flame rollout or inefficient firing. Its robust solenoid design and die-cast construction are built to withstand the thermal stress common in mechanical rooms, providing long-term reliability for hydronic heating applications.
- Precise Pressure Regulation: Factory-set for 4" Water Column to ensure consistent natural gas delivery and optimal burner performance.
- Broad Compatibility: Specifically designed for Laars Heating Systems, fitting popular models like the MiniTherm and Mighty-Stack commercial units.
- High-Flow Capacity: Equipped with 3/4" NPT connections to handle the BTU requirements of residential and light commercial boilers.
- Standard Electrical Specs: Operates on a standard 24VAC control circuit, making it compatible with most existing furnace and boiler transformers.
- Reliable HSI Integration: Engineered to work seamlessly with hot surface ignition controls for dependable startup cycles.
Common Questions
Is the Laars RV2001900 compatible with Propane (LP) systems?
No, this specific model is calibrated for natural gas at 4" WC. Using this valve with Liquid Propane without a certified conversion kit can cause dangerous combustion issues and equipment damage.
What are the inlet and outlet sizes for this valve?
This valve features standard 3/4 inch NPT threaded ports for both the inlet and outlet, providing the necessary gas volume for larger heating appliances.
Can I use this gas valve in a 120V system?
No, the RV2001900 is an electrically actuated valve designed specifically for 24V AC/DC control circuits. Applying 120V directly to the solenoid will result in immediate component failure.
