  • Patent number: 10377615
    Abstract: This invention relates to a sectional hydraulic valve and a truck mounted forklift incorporating the distributor. The sectional hydraulic valve comprises an inlet cover, a plurality of hydraulic sections and an end cap. The hydraulic sections each having a pump gallery, a tank gallery, an A port, a B port, a spool and a remote pilot gallery. The end cap comprises a pump port coupled to the pump gallery, a tank port coupled to the tank gallery and a connecting conduit between the pump port and the tank port. The end cap further comprises a remote pilot gallery port coupled to the remote pilot gallery, a fluid passageway between the remote pilot gallery port and the connecting conduit, and a valve assembly operable to selectively permit or restrict flow of hydraulic fluid between the connecting conduit in the end cap and the remote pilot gallery in the hydraulic section.
