The GateKeeper Series valve design employs a cast aluminum body, a linear drive mechanism, a counter-plate sealing mechanism, and an elastomer shaft seal.

The body is cast using the VaPore process which tightly controls each material input and process step to deliver a casting that is free of porosity.

1 GateKeeper Aluminum Gate Valves 250 mm Air-Operated 100 mm Air-Operated 63 mm Air-Operated The GateKeeper Series Aluminum Gate Valves are economical, reliable vacuum shut-off devices designed and manufactured by Varian. The valves provide a low-cost, low-particle, low profile means of isolating a high vacuum pump, and are a less expensive alternative to stainless steel valves. The GateKeeper Series valve design employs a cast aluminum body, a linear drive mechanism, a counter-plate sealing mechanism, and an elastomer shaft seal. The result is a clean, economical, smoothly actuated valve. The body is cast using the VaPore process which tightly controls each material input and process step to deliver a casting that is free of porosity. A reliable high vacuum shaft seal eliminates the need for a bellows. The linear drive and counter-plate sealing mechanism have been designed to minimize metal-on-metal contact. The assembly is an elegant mechanism that uses a small number of precisionmachined components. The required sealing forces are generated with a minimum of moving parts, and without adjustment screws. As a result, very few particles are generated within the valve. The Varian aluminum gate valve has a small flange face-to-face profile. ISO/F flange details are machined into the cast body to provide the convenience of standard ISO claw clamp connections. Features Cast aluminum body using VaPore process for vacuum integrity Low-cost, lightweight, high vacuum compatible valve High vacuum shaft seal no bellows Trouble-free operation Extruded aluminum air cylinder with internal dampening High cycle life to reduce shock Precision ball bearings guided in contoured ramps Quiet, low vibration valve actuation Seal plate assembly traveling on guide rails no rollers Very low particle generation contacting aluminum casting No seal plate adjusting screws that wear into the aluminum casting No adjustments required to provide the necessary sealing force Highly repeatable, long-lasting seal Small flange face-to-face dimension Convenience for system design and installation Remote and visual position indication switches Ease of operation 1
