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.

Smart, stylish, circular: polycotton recycling with Circ
Resource-efficient fashion has been a long-sought ambition amid the fashion industry’s considerable contributions to global carbon emissions. The need to close the loop by recycling textile fibers into virgin-like materials is higher than ever but seemed like a distant dream until now: Circ, GEA’s American customer and pioneer in the field of textile recycling, might be rewriting the future of the fashion industry.
New food tipping point
Alternative proteins are promising – yet still expensive to produce. The usual response is that scaling up will solve this issue. But what if the solution was really about getting better, not just bigger? From more efficient, high-yield processes to upcycling waste heat, engineers are reshaping how we grow food.
