DIN 11864 and DIN 11853 Aseptic Clamp Connection

The DIN 11864 and DIN 11853 Aseptic Clamp Connection from VTY factory has been developed by the German hygienic industry to meet the exacting needs of the pharmaceutical, food and fine chemical industries. 

DIN 11864 → Long ends, suitable for permanent aseptic piping systems requiring welding integration.

DIN 11853 → Short ends, ideal for compact or frequently reconfigured aseptic lines.

Defines Aseptic Clamp Connections specifically engineered for hygienic and aseptic environments, such as in the food, pharmaceutical, and biotechnology industries. A complete Aseptic Clamp Connection is consisted of a Clamp Nut, a Clamp Liner, an O-ring and a Heavy Duty Clamp.

These connections from VTY utilize a clamp mechanism that enables rapid assembly and disassembly, making them ideal for systems that require frequent cleaning, maintenance, or reconfiguration.

Real application

DIN 11864 is preferred in biotech fermentation skids; DIN 11853 is widely chosen in dairy and liquid filling lines where space is constrained.

Key Features

Aseptic clamp coupling.

Features tool-less assembly paired with a dead-space-eliminating sealing design compliant with DIN 11864.

Optimized for systems needing regular, rapid connection and disconnection.

FAQ

Q1: What is the difference between DIN 11864 and DIN 11853?

A: DIN 11864 has longer weld ends, better for permanent aseptic piping. DIN 11853 has shorter ends for compact systems.

Q2: Can VTY produce non-standard sizes?

A: Yes. VTY supports custom-engineered aseptic connections based on drawings.

Q3: Are these clamps compatible with other EU standards?

A: Yes. VTY also manufactures SMS, 3A, ISO, IDF, RJT, and DIN11851 variants.
