Vacuum regulators can be adjusted mechanically. They guarantee a precise setting with high repeatability. Vacuum regulators compensate for pressure differences of vacuum generators caused by their design.
Pressure-reduction valves are used to set a specific output pressure when the pressure on the input end (input pressure) is higher than necessary.
Manometers measure and display the vacuum in analog form. They can be used for all vacuum applications because of their standardized dimensions and connections.
