The Wacker Neuson Adjusting Valve is a genuine OEM component designed for CUB700 and HI750G indirect-fired air heaters. Sourced directly from Wacker Neuson, this adjusting valve meets the exact specifications of the original part and installs as a direct replacement in the gas train or fuel control circuit of these heater units. It is confirmed to fit the CUB700 skid-mounted indirect-fired heater as well as HI750G heater models, including standard and skid-mounted NG/LP configurations.
Key Features
- Genuine OEM Fuel Control Accuracy — Manufactured to Wacker Neuson's exact tolerances for proper gas flow regulation, ensuring the valve opens and closes at the correct pressure thresholds for these heater models.
- Direct Drop-In Replacement — Engineered to match the original valve's port sizing and thread specification, allowing straightforward installation in the existing fuel control assembly without modification.
- Confirmed Fitment — Compatible with the CUB700 skid-mounted indirect-fired heater and HI750G indirect-fired air heater series, including NG/LP and 3x16 configurations.
- Stable Heat Output — A correctly functioning adjusting valve maintains consistent fuel delivery to the burner, supporting steady, controlled heat output across the operating range of these indirect-fired units.
- Fuel System Safety — As a fuel control component, using the correct OEM-spec valve is essential to safe operation; an out-of-spec or failed valve can cause erratic flame behavior or unsafe pressure conditions in the gas train.
The adjusting valve regulates the flow of gas entering the burner assembly of an indirect-fired air heater, controlling the fuel pressure or flow rate to achieve the correct combustion mixture. On heaters like the CUB700 and HI750G, this valve is a critical part of the gas train — if it sticks, leaks, or fails to hold calibration, the heater may produce uneven heat, fail to ignite reliably, or trip safety shutdowns. Replacing a worn or faulty adjusting valve restores precise fuel control and ensures the heater performs within its intended operating parameters.
