Vacuum and pressure gauges
The measurement method is based on the Bourdon spring principle using section tubes in a special copper alloy. Movement of the free end of the spring is amplified and transmitted to the pointer. Units are enclosed in a sturdy case with a clear protective disc. Available versions: radial or coaxial connectors, built-in or external flange, dry or glycerine filled. Except Ø 40 mm, all models have a double scale dial. Manufactured in compliance with EU safety and measurement standards.

Vacuum adjustment valves
When valves reach a pre-calibrated vacuum degree they introduce atmospheric air into the circuit to prevent increase beyond set value and keep it constant. Can be used as regulators only on circuits with one vacuum pump and one use (or multiple uses at same vacuum degree). Common use as safety valves on high-vacuum tanks or vacuum cup lifting systems. Vacuum level adjusted by rotating knurled bush; fine thread ensures accurate calibration. Operating temperature range -20 °C to +200 °C.

Vacuum regulators
Control and maintain vacuum constant at pre-set value (secondary vacuum) regardless of source flow and fluctuations (primary vacuum). Operate by membrane-piston exploiting differential between secondary vacuum and atmosphere. Unlike adjusting valves, reducers do not release air into circuit, enabling multiple grip points at different vacuum degrees from a single source. Vacuum adjusted manually by knurled thumb screw.
