Trane VAL3519 Gas Valve

The Trane VAL3519 is an OEM 1/2" 24V Natural Gas Valve engineered for precise fuel regulation in residential and light commercial heating systems. As a veteran-grade replacement part, this dual-redundant solenoid valve ensures reliable ignition and consistent manifold pressure, effectively eliminating issues like delayed ignition or intermittent burner hangups. The unit features a standard 1/2-inch NPT inlet and outlet, designed for seamless integration into existing gas trains without the need for complex manifold reworking. Running on a standard 24VAC control circuit, the Trane VAL3519 is a direct fit for many Trane and American Standard furnace models, including popular high-efficiency series. Professional technicians prioritize this valve for its durable internal components that resist debris buildup, maintaining a steady BTU output and maximizing combustion efficiency. When troubleshooting a furnace gas valve replacement, this OEM component provides the specific flow characteristics required to meet factory specifications and maintain safe operating parameters for the heat exchanger. Key Benefits:

• OEM Precision: Specifically calibrated for Trane gas furnace applications, ensuring exact manifold pressure and gas flow rates.
• Enhanced Safety: Built with dual-head redundant solenoids to prevent gas leakage and ensure positive shut-off.
• Simplified Installation: Standard 1/2 inch NPT threads and 1/4" spade terminals facilitate a quick swap-out during service calls.
• Universal Compatibility: Widely used in natural gas heating systems requiring 24V ignition control.

Common Questions:

• Can this valve be converted to Propane (LP)? Yes, but it requires a specific LP conversion kit (sold separately). Never attempt to use this on propane without the correct orifice and spring kit.
• How do I verify if the valve is receiving power? Use a multimeter to check for 24VAC across the terminals during the ignition sequence once the inducer motor and pressure switches have cleared.
• Does this include the gas pipe nipple? No, this is the valve body only. Use high-quality pipe dope on the male threads, ensuring no sealant enters the valve inlet.
