Claim 11:
12. The hydraulic control assembly of claim 10, wherein the hydraulic valve includes:
a cage defining a plurality of cross holes and an axial bore,
a movable member disposed within the axial bore of the cage and axially movable over a range of travel with respect to the cage between a closed position in which the movable member occludes the cross holes to fluidly isolate the first port and the second port from each other and an open position in which the first port and the second port are in fluid communication with each other through the cage, and
a spring arranged with the movable member to generate a spring force against the movable member to bias the movable member to the closed position such that the flow of hydraulic fluid from the first port to the second port is blocked until the load pressure at the first port is sufficient to overcome the spring force to move the movable member to the open position; and
wherein the check assembly is arranged such that the load pressure at the first port acts upon the movable member of the hydraulic valve through the hollow interior of the check poppet, the poppet guide, and the check spring.
