Reznor 196981 Gas Valve

The Reznor 196981 Gas Valve is an essential OEM replacement component engineered for single-stage natural gas unit heaters and duct furnaces. Designed with a standard 3/4" NPT connection, this 24V gas valve operates at a 3.5" water column (WC) pressure rating to ensure precise fuel regulation and reliable combustion performance. As the direct replacement for 8419-75 and the VR8305K4241, this valve is critical for maintaining the safety sequence of your heating equipment.

This component is specifically used in Reznor UDAP, UDAS, UDBP, and UDBS series models (sizes 225-400), as well as UBX, UBZ, UDX, and UDZ units. For technicians performing unit heater troubleshooting, this valve ensures that the manifold pressure remains consistent, preventing common ignition failures or erratic clicking during the heating cycle. Its rugged construction is built to withstand industrial environments, providing a long-term solution for maintaining HVAC system uptime.
