Overview

The Suburban 525042 gas valve regulates propane flow to the main burner on SW-series water heaters, ensuring consistent ignition and flame quality. If your heater is struggling to light, dropping out, or showing unstable flame characteristics after you’ve verified the igniter/sensor, replacing a weak or sticking gas valve is the proper fix.

Key Features

• OEM Safety & Fit: Direct replacement for Suburban SW-series valves—no adaptations.
• Stable Flame Control: Correct pressure and flow for reliable ignition and recovery.
• Service Friendly: Standard NPT connections; designed for factory orifice/burner assemblies.
• 12V Control: Works with the heater’s control board for safe opening/closing.

Compatibility

• Series: Suburban SW (D/DE/DEL/DEM variants; verify against your serial/build sheet).
• Example Fit: Common on SW6 / SW10 / SW12 / SW16 family, including SW12DE.
• Burner/Orifice: Pair with the correct SW burner tube/orifice for your model.
