Abstract:
A valve is disclosed for use with a hydraulic circuit including a valve block, a central bore and an actuator passage formed in the valve block, and at least one of a supply and a drain passage. The valve also includes a control spool movable to selectively connect the actuator passage and at least one of the supply passage and the drain passage. The control spool includes a base end, and a tip end with a tapered outer surface. The valve also includes a first actuator configured to selectively direct pilot fluid to the tip end of the control spool, and a second actuator configured to selectively direct pilot fluid to the base end of the control spool. The first and second actuators each include a primary axis oriented generally orthogonal to an axis of the control spool, and are located at opposing sides of the control spool.
