2055290 SPOOL For HITACH ZW310-5A QSM11

The spool is a mechanical component used to control the flow and direction of fluids—typically hydraulic oil or air—within a valve or actuator system. It is a cylindrical part that moves within a valve body to open, close, or redirect flow channels. Spools are essential in hydraulic and pneumatic systems, especially in construction machinery, industrial equipment, and automotive applications. By shifting position, the spool directs fluid to specific ports, enabling precise control of actuators like cylinders or motors.

The spool is a mechanical component used primarily in hydraulic, pneumatic, or valve systems to control the flow and direction of fluids or gases. It typically consists of a cylindrical rod with grooves or lands that slide within a valve body to open or close specific flow paths. By shifting positions, the spool directs fluid to different ports, enabling movement or operation of actuators, pistons, or motors. Spools are essential for precise flow control in systems like excavators, loaders, and other machinery.
