Vacuum Check Valves

Brand: EDCO USA

Vacuum check valves are designed to prevent reverse flow of ambient air into a vacuum system by holding vacuum downstream whenever the vacuum source is removed or lost. 

Internally, a normally closed valve allows vacuum flow in the pump direction but seals off when vacuum flow ceases. 

When a vacuum check valve is used in a system, some provision must be made to release the trapped vacuum to release the workpiece.
