No Return Valve - NRV
Hygienic check valve designed to reliably prevent backflow in sterile process systems
Why this solution?
In hygienic processing systems, uncontrolled backflow may cause contamination, pressure fluctuations or process instability.
The Connectors NRV provides automatic pressure-dependent closing, reliably protecting sensitive production processes from reverse flow.
Solution advantages
Hygienic design
Automatic closing function
Suitable for CIP/SIP processes
High process reliability in sterile applications
Product features
Reliable backflow protection
Opens at defined differential pressure and closes automatically when flow reverses.
Hygienic sealing concept
Aseptic sealing geometry minimizes dead space and supports full cleanability.
Flexible connection options
Available with Tri-Clamp, DIN 11864 or other hygienic connections.
