20.3 VATTERFLY Valve
Butterfly Valves
The core element of the 20.3 VATTERFLY valves is the specialized VATTERFLY technology. The VATTERFLY closing mechanism differs significantly from conventional butterfly valves, as the disc moves during the closing process without coming into contact with the valve body. This prevents the risk of particle release that could have accumulated from gas by-products. For additional safety, the mechanism can be mechanically locked in both the open and closed positions, similar to a gate valve.
These features make the 20.3 particularly suitable for isolation requirements in contaminating and aggressive processes. Tested in thousands of demanding applications under various process conditions, the 20.3 series has proven its outstanding reliability.
