1. General
The shut-off and balancing valves belonging
to the Vexve X series have integrated press fit
connections. They are designed to provide the
optimal shut-off and balancing functionality
for heating and cooling networks in buildings.
Steel valves are suitable to use with EN 10305
thin-walled steel pipes. Stainless steel valves are
suitable to use with EN 10312 thin-walled stain-
less steel pipes.
The steel valve (turquoise) is designed for clean
media, such as oxygen-free water or water–gly-
col mixtures.
