NOVIS – The cost-effective valve series for cryogenic applications

The Novis valve series 500 from STÖHR ARMATUREN offers a standardised and cost-effective valve for cryogenic applications for liquid nitrogen temperature (77 K/-196 °C).
Our series 500 has been designed for applications that do not require the complexity of vacuum jacketed installation.
The series 500 is built to high specifications and quality offering high flow rates where low maintenance and high integrity sealing is required, using reliable gland packing rather than bellow sealing.
The STÖHR ARMATUREN series 500 offers considerable benefits through reduced delivery time and reduced cost at acquisition and installation on site.
