Abstract
A bi-directional metering valve assembly is provided to selectively direct hydraulic fluid under high pressure to a load. The assembly includes a valve block defining a first port that receives hydraulic fluid from a source, and a second port that directs hydraulic fluid toward a load. A rotatable valve member defines first and second apertures in an axial face that may be placed in selective communication with the first and second ports, respectively, to direct hydraulic fluid from the source to the load. At least one metering sealing assembly provides an interface between the valve block and the valve member. The metering sealing assembly includes a gasket that surrounds one of the first and second ports and defines a flange that is sized to completely overlap and seal the corresponding aperture. The valve member is operable to control the direction of fluid flow, and make fine adjustments to the hydraulic fluid flow rate.
