ABSTRACT:
A valve assembly is disclosed in two embodiments for selectively controlling pressurized fluid flow to operate a fluid operated working cylinder and piston. The valve assembly includes a valve body, groups of three bores operably paired in the body, biased plunger valves interposed in each of the bores, and a separate passage inter-connecting between each bore group on one side of the interposed valves. There is provided a pressure connection to a first one of the bores in each group on the other side of the interposed valves away from the passage and a first side cylinder connection to a second one of said bores in one of each pair of groups. The other cylinder connection is provided to a second one of the other one of each pair of groups of three bores while an exhaust connection is provided to a third one of the bores in each group. A control is operable for selectably actuating the interposed valves for proper inter-connection between the passage, valves and corresponding connection to provide either contraction, extension or a neutral condition for the working piston and cylinder.
