Dump Truck Control Valve Valve Design: This control valve is engineered for convenience and can be mounted in the cab. It offers four working positions: rising, intermediate stop, descent, and slow descent of the truck's load, improving ease of use and efficiency. Control: Dump Truck Unloading Control Valve with PTO Switch provides precision control that improves unloading accuracy and operational productivity. Wide Applicability: The Dump Truck Tipper Switch is versatile and can be mounted in the hydraulic system of various dump trucks, offering broad compatibility and efficient operation. Practical: The PTO Switch system features a selflocking function at the middle stop position, ensuring clear transposition and simple operation. This design enables easy control of dumping functions, increasing productivity and work efficiency. Use scenarios Construction sites: Use the fourposition valve to raise, pause at an intermediate height, and lower the bed gradually for controlled dumping of gravel or sand, reducing spill risk and material loss. Quarry or material yard operations: Mount the switch in the truck's hydraulic system to perform precise, staged dumping into bins or receiving areas, improving accuracy and workflow. Municipal or agricultural dumps: Employ the PTOcontrolled valve to manage loading and unloading of bulk materials with consistent, repeatable dump cycles, enhancing efficiency and safety.
