A proportional hydraulic control valve assembly has a pair of bores in a valve body with separate control spools in each bore. A pair of force feedback, linear actuators are mounted on the same side of the valve body and each actuator controls the movement of a different one of the control spools. O...

Beschreibung
Zusammenfassung:	A proportional hydraulic control valve assembly has a pair of bores in a valve body with separate control spools in each bore. A pair of force feedback, linear actuators are mounted on the same side of the valve body and each actuator controls the movement of a different one of the control spools. Only one of the control spools governs application of hydraulic power to a first work port of the valve assembly, while connecting a second work port to tank. Only the other control spool governs application of hydraulic power to the second work port of the valve assembly, while connecting a first work port to tank. The force feedback, linear actuators enable each spool to be received very tightly within the respective bore.
