■ Mechanism Vacuum Retention When a work-piece is apart from the vacuum cup, the float is pushed up by vacuum flow and seals on the housing. In this state, small amount of air passes through an orifice hole at the center of the float. Vacuum flow is checked. Suction State When the vacuum cup comes in contact and seals on a work-piece, Spring the float is pushed down Filter by a spring force as vacuum flow is reduced. This breaks the seal at Vacuum the float and vacuum flow Cup is in the full open state. Fitting Minimizing vacuum loss to maintain a certain vacuum level is critical to the performance...

Vacuum Retention Valve ■ How to install and disconnect In order to install Vacuum Retention Valve, tighten hexagonalcolumns with a wrench. Refer to the dimensional drawings for detail. Hexagonal-column for tightening fitting Detailed Safety Instructions Before using PISCO products, be sure to read “Safety Instructions” and “Safety Instruction Manual” and “Common Safety Instructions for Vacuum Series”. 1. Vacuum Retention Valve is not a check valve. Unless a vacuum supply side has the vacuum check function, Vacuum Retention Valve can not hold vacuum. Do not use it for a vacuum retention purpose....
