Title: Dual-sided slot valve and method for implementing the same
IPC: F16K51/02
Filed: 2000-02-29
Abstract: A dual sided slot valve is in a vacuum body between adjacent process and transport modules. Separate valves are provided for each of two valve body slots, one body slot being separately closed or opened independently of the other. The separate valves allow a vacuum in the transport module while an adjacent process module is open to the atmosphere for servicing. The valve allows access to an open valve for servicing the open valve in that one actuator motor stops the valve in an open, but not vertically-spaced, position relative to the respective slot. The open valve is more easily reached by a gloved hand of a service worker. A separate actuator motor moves the valve vertically down from the open position and away from the slot to expose the sealing surface around the slot for cleaning. The vertical distance of the vertically-moved valve from an access opening makes it difficult for the worker's glove to reach the valve for service. However, in the vertically-moved position the valve does not interfere with the ability to clean around the valve door. The dual sided slot valves are offset relative to each other to reduce the distance occupied by the valve body between the adjacent transport and process modules.
