Check valves and flow restrictors, as well as touch valves, increase Schmalz - The Company
the process safety and efficiency in a vacuum system.
Check valves interrupt the flow as soon as a certain volume
flow has been reached. This will turn off any suction cups in the Knowledge
gripper system that may not be covered completely. The system Vacuum
vacuum will remain intact.

Flow restrictors reduce the flow cross-section in the vacuum
system and are mainly used in gripper systems for handling Vacuum Suction Cups
porous workpieces. By reducing the flow cross-section, the system
vacuum remains intact even if the suction cups are not covered.

Touch valves open the suction channel with a spring-mounted
plunger when a workpiece is present at the suction cup. When Special Grippers
the suction cup is occupied (= workpiece present), the line for the
vacuum is opened. Touch valves do not protect the system from
Vacuum Grip- ping Systems
partially occupied suction cups.

Non-Return Valves

Non-return valves seal the vacuum system against leakage, for Mounting Elements
example, in the event of a vacuum failure caused by a power
outage. Thus, gripped workpieces are prevented from falling off
the gripping system.

Manual Valves
Filters and Connections
Manual valves are used for manual activation or deactivation
of vacuum or compressed air circuits or of individual suction
cups in lifting equipment. The valves are available as 2/2-way
or 3/2-way valves.
