Wacker Neuson 1000361930 Reversing Valve

The Wacker Neuson is a genuine OEM Reversing Valve designed for the TH627 series hydronic surface heater. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a correct, straight-forward installation with no guesswork. If your TH627 is showing uneven heating, loss of flow control, or erratic temperature distribution, the reversing valve is a primary suspect and this is the part to have on hand.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's original valve specifications, including correct port sizing, sealing surfaces, and flow-rate calibration for the TH627's hydronic circuit.
• Direct-Fit Replacement — Engineered to connect directly into the existing hydronic plumbing of the TH627 without adapters or line modifications, matching original thread pitch and body dimensions.
• TH627 Series Compatibility — Verified fitment for the TH627 hydronic surface heater (418-02), cross-referenced against Wacker Neuson spare parts list 418-02.
• Restores Proper Heat Distribution — A correctly functioning reversing valve directs heated fluid flow through the system blanket evenly; a failed valve causes cold zones, overheating in isolated areas, or complete loss of circulation control.
• Fuel System and Heat Circuit Safety — Proper valve seating prevents pressurized fluid leaks within the hydronic loop, protecting operators and the surrounding work surface from uncontrolled heat or fluid release.

The reversing valve controls the direction of heated fluid flow through the hydronic circuit in surface heating systems like the TH627. By switching or regulating flow direction, it allows the operator to manage how heat is distributed across the connected blanket or mat — critical for curing concrete or thawing frozen ground evenly. When the valve fails or sticks, fluid may bypass zones entirely or flow in an unintended direction, leading to inconsistent surface temperatures and potential damage to the work area or the heater itself.
