VARIVENT® VADĪBAS VĀRSTI

Jaunais GEA VARIVENT® Mixproof MX tipa vārsts piedāvā inovatīvas tehnoloģijas kā būtiskus uz nākotni orientētas drošības koncepcijas elementus. Tas piedāvā tādu produktu drošību, kas ievērojami pārsniedz iepriekšējās prasības.

Maximum process safety
The optimized physical design of the leakage cavity creates a negative pressure. Should a seal fail, the product is removed by vacuum and guided to the periphery without the risk of contamination (Venturi effect).

Maximum pressure relief
Thanks to specially shaped balancers in both pipelines, the valve remains stable in the closed position even in the event of water hammer and, on the other hand, retains its full ability to act even in the case of hydraulic lock or thermal expansion of the medium.

Maximum valve monitoring
Up to four feedbacks can be applied to ensure exact control and documentation of the valve status at all times.

Maximum cleaning efficiency
The uncompromising hygienic design of all components ensures maximum efficiency in valve cleaning, now enhanced by automatic external cleaning of the lower balancer when the lower valve seat is lifted.

Maximum compliance
The specially improved valve technology of the new GEA VARIVENT® Mixproof valve type MX fulfills the world's strictest design specifications for hygienic valves (3A, EHEDG).

State of the art: Maintenance-free actuator
Closed actuator housings, thoroughly protected by specially designed piston seals - designed to be maintenance-free. The robust design supports uninterrupted process operation and saves valuable time and operating costs.
