Summary:A control module for controlling an operation of a hydraulic actuator that is associated with an earthmoving machine includes a body. The 5 body has a spool chamber and a load sensing passageway associated with the spool chamber. The body also has a spool positioned axially, and at least partially, within the spool chamber. The spool is spring-biased by an end cap 408 located at a first end of the body. The body also has a pair of electrohydraulic spool actuators that are located at a second end of the body and operable to 10 axially displace the spool within the spool chamber. The pair of spool actuators are positioned in parallel and disposed adjacent to one another. The body also has an inlet chamber that is disposed parallel to the spool chamber and in selective fluid communication with the spool chamber via a spool supply passageway.
