    Abstract: A load lock valve (72) for a hydraulic system (44) is disclosed. The load lock valve may have a block (63) with a first bore (88), and a body (90) disposed within the first bore. The body may have a second bore (82), and first and second first radial ports (96, 98) in fluid communication with the second bore. The body may also have a valve seat (100), and a poppet (74) disposed within the body. The poppet may have a nose end (102), a control end (104), a balance passage (80) extending from the control end toward the nose end and terminating short of the nose end, and a third radial port (106) in fluid communication with the balance passage. The load lock valve may further have spring (78) configured to bias the poppet toward the first opening. The control end of the poppet is fluidly communicated with the first radial port when a sealing surface at the nose end is against the valve seat.
