The XCMG Heater Hot Water Valve (P/N 250300125, Dwg ZL50.26.5) is a genuine OEM manual shut-off cock specifically designed for the cabin heating systems of XCMG’s 5-ton class wheel loaders. Identified by the specification ZGZ3/8" (Cylindrical Pipe Thread, 3/8 inch), this valve is installed in the coolant circulation line connecting the engine to the dashboard heater core. It allows the operator to manually control the flow of hot engine coolant into the cabin heater, enabling efficient defrosting and thermal comfort during cold-weather operations.
Structural Design & Material
Premium Brass Body: Constructed from high-quality brass (copper alloy), offering superior corrosion resistance against engine coolant (antifreeze/water mixture) compared to standard steel. This prevents internal rust particles from clogging the heater core.
