Explosion-proof and with Zinc-Nickel surface treatment
The evolution of the markets' needs along with our willingness to serve at best our customers have led us to expand our offer with ex-proof versions and/or with Zinc-Nickel surface treatment.
In the first case we are talking about components compliant with the ATEX 94/9/CE directive. These proportional valves are suitable for the use in environments characterized by a potentially explosive atmosphere belonging to the ATEX II 2GD classification for gases and dusts.
The Zinc-Nickel finishing on the other hand ensures a salt spray resistance up to 600 hours (test performed according to the UNI EN ISO 9227 protocol and test validation done in compliance with the UNI EN ISO 10289 norms).
