Lockout valve

A lockout valve operable to control fluid between two components, the lockout valve comprising:

• a housing including an intake port spaced apart an outtake port, and wherein the housing further includes a flow passage in communication with an exhaust port;
• and
• a slide slidably mounted to the housing, wherein the slide is slidable between an open position and a closed position, the slide including an upstream surface and a downstream surface, the slide further including a vent disposed on the downstream surface, and a through port extending between the downstream surface and the upstream surface, and wherein when the slide is in the open position, the through port is disposed between the intake port and the outtake port so as to provide a passage for fluid, and wherein when the slide is in the closed position, the vent is disposed between the intake port and the outtake port and in communication with the flow passage, wherein the upstream surface prevents fluid from moving downstream the lockout valve, and wherein pressure downstream the lockout valve forces fluid downstream of the lockout valve to escape through the vent to the flow passage and out the exhaust port.
