R215-7 Travel Motor Main Relief Valve

The R215-7 Travel Motor Main Relief Valve is a core pressure protection component specially designed for the travel hydraulic system of R215-7 construction machinery. Tailored for excavator heavy-duty travel start-stop, road bump impact and high-frequency continuous operation, it is also compatible with auxiliary hydraulic units of industrial PU foaming equipment. It is widely applied in medium excavator travel hydraulic units, high-pressure industrial casting equipment and automatic continuous PU foaming lines. It locks the rated travel system pressure and releases instantaneous overpressure in real time, effectively solving common faults such as travel jitter, motor overheating and insufficient driving power to protect travel motors and hydraulic pipelines. Fully compatible with complete PU Foaming Hydraulic Components, it seamlessly matches all linear mixing head hydraulic modules and adapts to low and high-viscosity PU material delivery for diverse production modes.
