Work sections:
Hopper top door, tailgate, arms, forks and pack circuits are controlled by a work
section dedicated to each function. Air actuators attached to each of the work sections shift the
spool in the desired direction to allow pressurized oil to operate the hydraulic cylinders. Returning
oil is allowed to escape to tank via the return passage, outlet section and return lines.
Outlet Section:
This section caps the bottom end of the valve bank to provide a path for
returning oil to travel to the return line filter in the tank.
