The valve block directs hydraulic pressure to the actuators via solenoid operated directional control valves. A solenoid 
operated pressure control valve regulates the required pressure to the actuators. The three valve solenoids are 
controlled by signals received from the ACE ECU. A pressure transducer monitors the pressure delivered by the 
pump. A replacable high pressure filter is installed into the lower face of the valve block and filters fluid before it 
reaches the valves.

The valve block is located on the outside of the right hand chassis longitudinal. The valve block is secured to the 
chassis with three bolts and rubber bushes. The rubber bushes isolate the valve block from the chassis, preventing 
hydraulic noise from the valve block transmitting through the chassis and body.
