Product Overview
SLZ14750667H is a lift-pneumatic control valvefor Haiwo hydraulic systems, installed in the cabof a dump truck, and driven by hydraulic directioncontrol via a handle pneumatic control method,enabling cargo box lifting, mid-course locking,and falling. It is a core control component for thehydraulic lifting system of a dump truck.
Core ProductAdvantages
Precise control of gears
The lifting/middle locking/lowering three levels are
clearly defined, ensuring smooth blockage withoutjamming, precise container start and stop control, andsafer unloading operations. High-strength sealing forair leakage prevention
Built-in oil-resistant and wear-resistant sealing ring,the valve body is precisely die-cast. It prevents
pressure relief, gas leakage, and eliminates issues
such as weak lifting and self-deactivation during timefluctuation.
Original vehcle non-destructive replacement
The three-hole airway layout is exactly the same as thatof Haiwo’s original factory valves. The pipeline is
directly connected, no need for hole or wiring
modification, convenient installation, and ready for
immediate use after replacing the old ones.
Durable and durable, suitable for heavy truck operating condltions
The aluminum alloy valve body is corrosion-resistant and
vibration-resistant, suitable for harsh construction sites and
soil transportation environments, and has a longer service life.
Common Fault Adaptation
It can resolve faults such as slow and weak lifting,cargo boxes falling off automatically, handle gearjamming, valve body leakage, failure of liftingfunction, and pressure relief in the airway.
Installation Precautions
. Close the air tank valve and drain the residual air pressure from the pipeline before disassembly and assembly.
Remove the old valve again;
2. The air circuit joint is wound with the raw material belt to prevent leakage in the later stage.
3. After assembly, repeated testing of lifting, intermediatestop, and drop levels is completed, and confirmation thatthey are considered normal before being put back into use;
4. If the air passage is contaminated with water or oil for a longtime, it is recommended to simultaneously clean up theaccumulated water in the gas storage pipe to extend thevalve’s service life.
