Control valve assembly for load carrying vehicles |
摘要 |
A control valve assembly is provided for a load carrying vehicle that includes a storage space and a dumping mechanism. The control valve assembly includes a housing and a sliding valve positioned within the housing and movable between a first position, and a second position. The sliding valve includes a first piston that defines a first piston first surface and a first piston second surface, and a second piston that defines a second piston first surface and a second piston second surface. The first piston second surface faces the second piston first surface. A pilot system includes a first pilot passage in fluid communication with the first piston second surface to selectively actuate the sliding valve toward the first position, and a second pilot passage in fluid communication with the second piston first surface to selectively actuate the sliding valve toward the second position. |
