ABSTRACT:
A valve system for controlling the direction of flow of pressurized fluid. The valve system includes a valve housing, with an inlet port for receiving pressurized fluid therein, a first cylinder port and a second cylinder port. The housing is further constructed with first and second exhaust ports. Passageways connect the inlet port to the first cylinder port and to the second cylinder port. Passageways also extend from the first cylinder port to the first exhaust port and from the second cylinder port to the second exhaust port. A pair of pistons and corresponding poppet valves are slidable within the housing to control flow of fluid through the passageways. In one embodiment, the pistons and poppet valves are moved by communicating fluid pressure from the inlet port either above or below the pistons. In an alternative embodiment, the pistons and popper valves are mechanically actuated.
