The first Vacuum-M type was introduced in 2006. In 2020, the Vacuum-M valve has been upgraded to fit the challenges of today. The challenge of a standard vacuum valve has always been the pressure drop during its functioning. To handle the pressure drop, the standard vacuum valves and their performance have been changed.
