The Wacker Neuson Valve Solenoid is a genuine OEM component designed for the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 90HD indirect-fired air heater series. As a direct factory replacement, this solenoid valve is built to the exact electrical and mechanical specifications required by Wacker Neuson heater systems. It slots directly into the fuel delivery circuit, ensuring correct valve actuation without additional modification. Verify your heater's model number before ordering to confirm compatibility across this range of units.
Key Features
- Genuine OEM Electrical Spec — Factory-sourced solenoid valve engineered to the correct coil resistance and voltage rating for Wacker Neuson indirect-fired heater fuel systems.
- Direct-Fit Replacement — Designed to connect directly into the existing fuel circuit on HDR 45, HD 50, HD 70, HI35, HI 90, and HI 90HD heaters using the original mounting and wiring interface.
- Precise Fuel Flow Control — Maintains accurate on/off fuel delivery to the burner assembly, which is critical for consistent heat output and proper ignition cycling in cold-weather applications.
- Fuel System Safety Compliance — A correctly functioning solenoid valve ensures fuel flow is fully shut off when the heater is not firing, reducing the risk of uncontrolled fuel release in the heating circuit.
- Wide Heater Family Coverage — A single part number covers six indirect-fired heater models across the HDR and HI series, making it a versatile stock item for fleet operators and service technicians.
The solenoid valve controls the flow of fuel to the burner in an indirect-fired air heater. When the heater calls for heat, the solenoid receives an electrical signal that opens the valve and allows fuel to reach the burner; when the call for heat ends, the valve closes to cut off fuel supply. A failed or sluggish solenoid valve can cause hard starts, intermittent heating, failure to ignite, or an inability to shut the burner off cleanly — all of which compromise heater performance and safe operation on the jobsite.
