Valve Test Unit (VTU)
The Valve Test Unit (VTU) can be used to perform tests on “Degassing Valves” Degassing valves are used
on some coffee and food products to prevent a pressure build-up inside the product packaging.
The VTU can be used either to test the cracking or burst pressure of the valve or to verify that there is no
“reverse leakage”.
Setting Up
1. Connect the supplied hoses between the “Clamp”, “Feed” and “Sense” connectors on the Lippke
4000/4500 to the corresponding IN connectors
 on the VTU.
2. Connect the hoses from the measurement accessory f.ex. test head on the Stand for Closed
Packages to the “Clamp”, “Feed” and “Sense” OUT connectors
 on the VTU.
NOTE! The “Clamp” connections are only to be used in cases where you want the Lippke
4000/4500 device to control the lower clamp bar on the PPC 300 II or for a MultiCheck
system.
