Operating Principle

Varibell® is a rotary quarter turn valve. The regulating element is a bell shaped plug, featuring tear drop shaped apertures machined into both inlet and outlet but laterally reversed. During opening, this plug rotates and simultaneously uncovers the two tear drop apertures giving fine flow adjustment with a 2 stage pressure reduction across both seats.

As the plug further rotated the profiled apertures gradually become circular permitted an increasing flow. At full capacity the apertures are circular over the whole pipe diameter and the flow is unrestricted.

The bell shaped plug with a slope angle outside the interlock is being pressed into the valve seat by means of the spring force in the bottom cover.

During rotation the seat simultaneously acts as a "friction bearing", absorbing the friction forces over a wide surface area and centering the control element under the action of the spring.

 

  • High turndown ratio of up to 1:10.000
  • Virtually zero pressure drop in the fully open position
  • Highest KV ratings (approx. 4 times the value in comparison to conventional globe control valves)

General Information

We offer valves according to the current DIN / EN but also to ASA / ASME standards in a wide range of sizes and pressure ratings.

As a rule, our flange connections are built according to DIN EN 1092-1 Form C with sealing surfaces according to DIN EN 1092-1 Form B1. The pressure ratings comprise the range from PN 16 to PN 400.

ANSI executions are built in accordance with ASME B16.5. The range is from Class 150 to Class 2500.

On request, valves can also be built e.g. with weld on ends or in accordance with internal factory standards.
