Abstract: A lockout valve operable to control fluid between two components is provided. The lockout valve includes a housing having a flow passage, an intake port, an outtake port, and an exhaust port selectively in communication with the flow passage. The lockout valve further includes a slide slidably mounted to the housing between an open position and a closed position. The slide includes a vent disposed and a through port extending through the slide. When the slide is in the open position, the through port is disposed between the intake port and the outtake port, providing a passage for fluid. When the slide is in the closed position, the vent is fittingly disposed between the intake port and the outtake port so as to prevent fluid from flowing downstream the lockout valve and to allow fluid pressure downstream the lockout valve to escape through the exhaust port.

Abstract: A lockout valve is provided having a valve body with an inlet conduit, a central chamber and an outlet conduit, to form a continuous passageway. The lockout valve also includes a slide mechanism slidingly disposed in valve slide channel to operatively control fluid flow through the passageway between an open position, an intermediate position and a closed position. The slide mechanism includes a plurality of flow apertures to restrict flow through the passageway. The front side of the slide mechanism includes a detent slot and the back side of the slide mechanism includes a longitudinally extending override slot having an upper portion positioned opposite the detent slot to form a continuous opening, and a lower portion that does not form a continuous opening. The valve further includes a detent mechanism for overriding the intermediate position of the slide mechanism including a detent override lever with a finger member extending from an edge of the detent override lever.

Abstract: A pilot operated and pneumatically driven control valve assembly has a pair of pilot operated and pneumatically driven regulators to control the pressurization and venting of a pneumatic cylinder. The pilots of each regulator are alternately driven by a pair of normally open pilot operated valves each of which is in communication with a separate regulator to control the pressurization of that regulator. The pressure acting on the pilot of each regulator controls the flow of air through the regulator and the subsequent magnitude of the pressure within the pneumatic cylinder. Thus, varying the pressure in the pilot of the regulator varies the resulting pressure in the pneumatic cylinder in proportion to the pilot pressure. The pilot operated valves are alternately driven between open and closed positions to alternately drive the pilots of the regulators.
