Gas ballast - Pfeiffer Vacuum

4.1.6 Gas ballast. Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast. If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with …

EBV Gas Ballast Valves

The EBV Valves are solenoid operated, normally closed valves used to automatically switch on or switch off the gas ballast to an Edwards rotary pump.
