VARIVENT® CONTROL VALVES

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).

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.

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.
