  • Publication number: 20220403945
    Abstract: A valve for throttling gas flow from a semiconductor processing tool includes a valve body. A shaft extends through the valve body. The shaft defines an internal cavity and a first opening communicating with the internal cavity. A first deflector is positioned on the shaft proximate the first opening and directed at a first interface between the shaft and the valve body. A method for throttling gas flow from a semiconductor processing tool includes providing a gas in an internal cavity defined in a shaft of a valve and directing the gas through an opening defined in the shaft and communicating with the bore toward an interface between the shaft and a valve body of the valve supporting the shaft.
