Fitting & Flanges
Flange Connections & Fittings
The valve housings can be specified with a welded-on connection fitting.The seal which may be included corresponds to the sealing material of the valve.
VARIVENT® Flange Connections
VARIVENT® Flange Connection TK
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.
Pipe Fitting Acc. to DIN 11851
Complete Connection GK
A sealing ring G is used for sealing the pipe fitting acc. to DIN 11851.If a complete connection is ordered on a housing pipe end, the male end is welded onto the housing. The groove flange contains the sealing ring G. The liner (KO) contains the groove nut. The pipe fitting acc. to DIN 11851 can be ordered either as a complete connection (GK) or male end SC (GO)/liner SD (KO) as a connection fitting on a vertical port.
Hygienic Flange Connection Acc. to DIN 11853-2
Hygienic Flange Connection ASK
An O-ring is used for sealing the hygienic flange connection acc. to DIN 11853-2, 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,
Furthermore, the flange connection is centered by the design shape. The sealing geometry of the hygienic flange connection corresponds to the aseptic flange connection acc. to DIN 11864-2.
The hygienic flange connection (ASK) can be ordered either as a complete connection including bolts and nuts (ASK) or a hygienic groove flange (NFK)/hygienic flange (BFK) as a connection fitting on a vertical port. If a complete connection is ordered on a housing vertical port, the groove flange is welded onto the housing. The groove flange (NFK) contains not only the O-Ring but also the required connecting elements.
Clamp Connection (Tri-Clamp)
Clamp Connection CO
The clamp connection acc. to DIN 32676 is a widely used connection fitting, especially in North America. The connection uses a symmetrically structured clamp connection with a seal located in between it, and is secured by a clamp. The second clamp connection, the seal and the clamp are not supplied.

Around the world in seven questions: New foods we’ll love
Last year was not a year of hyped-up headlines for alternative proteins. Perhaps that is precisely why it was an important year for food biotech, the biotechnology behind everyday foods and ingredients. While the sector worked through a difficult funding environment, approvals were still granted, pilot lines set up and new platforms tested in the background. In short: headlines are turning into infrastructure. Frederieke Reiners heads GEA’s New Food business. She and her team work at the intersection of biotechnology and industrial food production. In this interview, she takes us on a world tour of food biotech in seven questions.
