Vacuum Check with Release Check: VC 18-RC & VC 12-RC

VC check valve with RC release check is used with a single suction cup so a non-porous, high value, work piece won’t be immediately dropped if the system vacuum source is lost. Depending on the condition of all vacuum system components, the trapped vacuum will eventually leak down. To increase the time delay interval, a volume chamber can be added to the auxiliary port. If the volume chamber is equal to twice the cup internal volume, the time delay interval will be approximately tripled, and so forth.
