Abstract
A valve system, including first, second, third and fourth ports, a first flow path connecting the first and second ports, a second flow path connecting the third and fourth ports, with valves connected in the first and second flow paths, and energizable to block the same. A third flow path connects the first and second ports and a fourth flow path connects the third and fourth ports. The third and fourth flow paths are more restricted than the respective first and second flow paths. A fifth flow path connects the first and fourth ports and a sixth flow path connects the second and third ports. When the third and fourth flow paths are open, the first, second, fifth, and sixth flow paths are blocked. When the first and second flow paths are open, the third, fourth, fifth, and sixth flow paths are blocked. When the fifth and sixth flow paths are open, the first, second, third, and fourth, flow paths are blocked.
