Key Features & Benefits
Smooth Spiral Rail Connection: Unlike conventional Dry Disconnect Coupling designs, male and female components connect via a smooth spiral rail. This design:
Minimizes dead space in the coupling pathway, reducing media residue buildup.
Simplifies cleaning and sterilization processes, critical for sanitary applications.
Versatile Sealing Options: Compatible with high-performance gaskets (FKM, NBR, FFKM, PTFE) to ensure leak-tight seals across diverse chemical and temperature conditions.
Robust Pressure Rating: Operates reliably within a working pressure range of 10–25 bar, suitable for most industrial process demands.
Flexible End Connections: Available with flange or threaded end connections for seamless integration into existing piping systems.
Product Functions
Couplings are purpose-built for environments where hygiene, chemical resistance, and process integrity are paramount. Typical use cases include:
Chemical manufacturing and processing plants.
Pharmaceutical production (e.g., API synthesis, formulation, and packaging).
Sanitary fluid transfer systems requiring frequent cleaning/sterilization.
