Abstract
A double-solenoid directional control valve comprising a valve body and a valve spool within the valve body, where the valve spool is configured to move within the valve body between a first position, a second position and a third position, where the third spool position lies between the first and second spool positions. In certain embodiments, the spool is maintained in the first and third positions by energizing at least a first or a second solenoid actuator, and where the spool is maintained in the second position by de-energizing both solenoid actuators.
