Laars Heating Systems R0059100 Gas Valve
The Laars Heating Systems R0059100 Gas Valve is a critical components for maintaining precise fuel regulation in high-performance hydronic systems. This 24V natural gas valve is engineered for standing pilot applications, featuring a 1/2" x 3/4" FPT connection (often adapted for 1/2" x 1/2" configurations) to ensure a secure, leak-free seat within the gas train. With a factory-set manifold pressure of 4" w.c., it provides the consistent flow required for optimal combustion in Laars JVT boilers, including the JVT050, JVT075, JVT100, JVT125, and JVT160 models. Built to withstand the rigorous duty cycles of commercial and residential heating, this OEM replacement gas valve eliminates ignition delays and irregular flame patterns caused by worn solenoid coils or internal diaphragm fatigue. For technicians performing a furnace gas valve replacement, this unit ensures seamless integration with existing 24VAC control circuits and thermocouple assemblies.
Key Benefits
- Precise Pressure Regulation: Pre-configured for 4" w.c. to maintain steady manifold pressure and prevent over-firing.
- Broad Compatibility: Drop-in HVAC replacement part for the Laars JVT series and various Teledyne Laars natural gas appliances.
- Robust Solenoid Design: High-duty 24V coils provide reliable opening/closing force to prevent the valve from sticking during cold-start cycles.
- Standardized Ports: Features a 1/2" inlet and 3/4" outlet (with reducing bushings frequently used) for versatile piping into existing manifolds.
Common Questions
Can I use the R0059100 for LP (Liquid Propane) conversion?
This specific model is calibrated for natural gas with a 4" w.c. setting. If converting to LP, a manufacturer-approved conversion kit must be used to change the regulator spring and orifices; otherwise, the burner will not operate at the correct BTU rating.
What are the symptoms of a failing Laars gas valve?
Common indicators include the inducer running without ignition, the standing pilot failing to stay lit despite a good thermocouple, or audible humming/chattering from the solenoid. If you measure 24V at the terminals during a call for heat but the valve does not open, the internal coil or diaphragm has likely failed.
Is this valve compatible with electronic ignition systems?
No, the R0059100 is designed for standing pilot systems. Intermittent pilot or direct spark ignition systems require a different redundant valve configuration to handle the specific timing of the ignition module.
