Vacuum units for air operated pinch valves

Vacuum units
for pinch valves

In order to use pinch valves, e.g. in vacuum conveying, it is recommended to install an AKOVAC vacuum unit.
The sleeve normally starts to contract at a vacuum of > 0.1 bar. The built-in vacuum unit creates a counter vacuum (vacuum compensation) within the valve body and thus forces the sleeve to remain completely open.

  • The completely constriction-free passage in the pinch valve will be preserved.
  • The wear and tear of the sleeve is reduced and thus the service life is increased.

The AKOVAC vacuum units are available in two versions:

In the Basic version, the closing pressure & vacuum level cannot be adjusted separately.
At a high vacuum, this simultaneously results in a high closing pressure and thus a higher load on the sleeve.
Components: solenoid valve, vacuum pump, silencer

AKOVAC Perfect
With the Perfect version, the closing pressure and vacuum level can be set separately. This increases the service life of the built-in sleeve.
Energy-saving switch-off of the vacuum pump when the desired vacuum level is reached.
The integrated digital pressure sensor enables the vacuum level inside the pinch valve to be displayed and automated by the customer.
Components (depending on version): vacuum pump, 5/2-way solenoid valve, quick exhaust valve, filter/pressure regulator, pressure regulator, two pressure gauges (pressure supply and closing pressure), digital pressure sensor (vacuum level in pinch valve), mounting bracket and all necessary hoses and fittings.
