A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

An electromagnetic valve manifold includes an electromagnetic valve including an output port, a manifold base including an output passage, and a spacer arranged between the manifold base and the electromagnetic valve. The spacer includes a spacer block including a shaft hole and a manual shaft accommodated in the shaft hole. The spacer block includes an output connecting passage that is connected to the shaft hole and connects the output passage and the output port to each other. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows for connection between the output passage and the output port through the output connecting passage, and a second switching position, in which the manual shaft blocks the connection between the output passage and the output port through the output connecting passage.

A system for exhausting hazardous stored energy from a pneumatic subsystem of a railcar, comprises: an air supply for delivering air to the pneumatic subsystem of the railcar; and an isolation valve interposed between the air supply and the pneumatic subsystem of the railcar. When the isolation valve is in a normal operating position, a supply port and a delivery port of the isolation valve are in fluid communication with one another, but when the sliding shoe is in the second position, the sliding shoe effectively closes access to the supply port, and the delivery port is in fluid communication with an exhaust port of the isolation valve. The isolation valve further includes a means for locking the sliding shoe in the second position.

A ball valve assembly includes an outer sleeve having first and second pillars and defining an outer sleeve hollow, a first notch, a second notch, and a third notch, wherein the first pillar of the outer sleeve at least partially defines and is positioned between the first and second notches, and the second pillar of the outer sleeve at least partially defines and is positioned between the second and third notches.

An electromagnetic valve manifold includes an electromagnetic valve and a manifold base. The electromagnetic valve includes a manual shaft. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows movement of the valve member relative to the valve hole, and a second switching position in which the manual shaft restricts movement of the valve member relative to the valve hole. The manual shaft includes a projection that is projected into and retracted from the valve hole. The valve member includes at least one recess in an outer surface of the valve member. The manual shaft is configured such that, in a state in which the manual shaft is located in the second switching position, the projection is projected into the valve hole and engaged with the recess, so as to restrict movement of the valve member.
