Festo ISV-1/8 33969 Vacuum Security Valve G1/8 Suction Safety Check

The Festo ISV-1/8 (Part Number: 33969) is a specialized vacuum security valve designed to increase the reliability of vacuum handling systems. Installed between the vacuum generator and the suction cup, this valve automatically closes off the line if a suction cup fails to make contact or leaks significantly. This ensures that the vacuum level is maintained for the remaining active suction cups in the system.
