Solenoid valves, which are controlled via electrical switch signals, are used for the control of compressed air or vacuum. These valves can be controlled directly as well as with pneumatic pilot operation.

Check valves close the vacuum lines of uncovered suction cups. This maintains the system vacuum. Flow restrictors constrict the vacuum line. They are used predominantly in the handling of porous parts.

Touch valves are mainly used for applications in which all suction cups are not always occupied. The sensing valve checks mechanically whether the suction cup is occupied and only then opens the vacuum line.

Non-return valves are used to protect the system. In the event of a power failure, for example, the non-return valve seals the vacuum system against leakage.

Manual valves are mainly used for manual activation or deactivation of vacuum or compressed air circuits or of individual suction cups in lifting equipment.

Compact valves are used to control and monitor vacuum systems. They are controlled via electrical switching signals. Important process data is transmitted to the control system via an integrated sensor unit. The integration of valve and sensor units makes them particularly suitable for applications with central vacuum supply.
