Varivent

Wherever liquid processing operations require sustainable product and process security, GEA VARIVENT® is the first choice for any system operator or planner. Varivent is a patented valve technology by manufacturer GEA Tuchenhagen. It is widely used in process plants with fixed tubing. For this reason, pressure gauges for use in process automation are usually available with Varivent connections, among other process connections.


An O-ring is used for sealing the VARIVENT® flange connection, and is given a defined compression by a metal stop. The O-ring is also protected by the special geometry of the recess from being pulled out at high flow rates.


The VARIVENT® flange connection (TK) can be ordered either as a complete connection including bolts and nuts (TK) or a groove flange (TN)/smooth flange (TF) as a connection fitting on a vertical port. If a complete connection is ordered as the connection fitting, the groove flange is welded onto the housing. The groove flange (TN) contains not only the O-Ring but also the required connecting elements.
