Vacuum regulators are used to adjust the vacuum degree and to keep it constant at the preset value (secondary depression) independently of the
capacity and of the oscillations of the vacuum degree of the pump or of the pumpset (primary depression).

Unlike vacuum adjusting valves, regulators do not introduce air into the circuit, this permits to produce more grip points at different vacuum values, from
one only depression source.

Their operating principle is based on the contrasting action between a pneumatic cylinder with short stroke and a fluctuating piston driven by the
pressure differential existing between the secondary depression and the atmospheric pressure.

In order to adjust the vacuum degree of the regulator it is necessary to operate on the pressure of the compressed air for feeding the pneumatic cylinder: higher is the pressure, higher is the vacuum degree, and vice versa.

Technical features:
• Supply pressure:
  from 0 to 3 bar(g) for the regulators Art. 11 .. 30;
  from 0 to 7 bar(g) for the regulators Art. 11 .. 80.
• Adjustable working pressure:
  from 800 to 1 mbar abs. for the regulators Art. 11 .. 30;
  from 980 to 1 mbar abs. for the regulators Art. 11 .. 80.
• Capacities: from 2 to 160 cum/h;
• Room temperature: from -10°C to +80°C.
• Mounting: any position.

Applications
The main use of the vacuum regulators is on the centralized plants where, independently of the vacuum degree of the plant, every grip can be
adjusted within that value. It is also necessary every time that the working depression has to be lower than the primary depression.
