Product Description P/N: R0385100
Description
The R0385100 is a one-stage spark-ignition natural gas valve rated for 24 V control voltage with a nominal 4 in-water-column pressure drop. It features a ½″ inlet × ¾″ outlet connection and is designed to regulate gas flow in boilers and other HVAC combustion equipment. Ideal as a direct replacement part for Laars systems using single-stage ignition, it ensures reliable fuel control and safe operation.

Information About R0385100
The R0385100 is part of Laars’ single-stage gas valve line configured for spark ignition natural gas burners. Operating at 24 VAC control voltage, it is designed for a nominal outlet pressure drop of 4″ W.C. (inches water column) in natural-gas applications. The valve uses a ½″ NPT inlet and ¾″ NPT outlet (or equivalent sizing) for flow connection. It is compatible with a number of Laars boilers in the JVS, JVSND, BWS and other series. The valve supports spark-ignited burners (versus standing-pilot) and is suitable for retrofit or replacement in existing systems.
Key Features:
- 24 V Control Voltage: Designed for low-voltage control circuits common in HVAC systems.
- Rated 4″ W.C.: Nominal outlet pressure drop of 4 inches water column for natural gas operation.
- Natural Gas Service: Factory configured for natural gas (not LP unless converted).
- ½″ × ¾″ Connections: Provides ½″ inlet and ¾″ outlet port sizing for flow compatibility.
- Spark Ignition Type: Suited for burners using spark ignition rather than standing pilot.
- Single-Stage Operation: Opens once for full-output burner cycle (on/off) rather than multi-stage.
- OEM Replacement Part: Designed for Laars equipment, enabling exact fit and function in matching models.
- Industrial Construction: Built for combustion service with durable body and internal components.
- Easy Installation: Common control voltage and port size facilitate direct swap-in replacement.
The R0385100 delivers the reliability and performance required for single-stage natural-gas burner control in commercial and residential boiler systems.
