Performance and Safety The Power TakeOff (PTO) function of this Proportional Control PTO Switch Valves system disengages automatically when the vehicle body is lowered, reducing wear and preventing stopping damage. A builtin warning light improves visibility and safety during operation. Precise Control for Unloading Dump Truck Unloading Control Valve with PTO Switches are engineered to offer precision control that improves the accuracy and efficiency of truck unloading, thereby boosting operational productivity. Practical and Reliable Operation The Dump Truck PTO Switch system features a selflocking mechanism at the middle stop position, providing stable, repeatable dumping and straightforward control. This practical design helps the user easily manage dumping functions, increasing productivity and work efficiency. CabMount Design and FourPosition Operation These valves are designed for cab mounting and provide four working positions that control rising, intermediate stop, descent, and slow descent of the truck's load, enhancing ease of use and operational efficiency. Compatibility, Size, and Performance Compatible with standard PTOequipped dump trucks. Compact cabmount design supports flexible installation in the vehicle cab. Built for durability and reliable performance in demanding jobsite conditions.
