The Adjustment Element (Control Bell)

Depending on application th Varibell® control element is available in differing versions:


a) Full Bell Typ:VG

This is the standard design. Most of the Varibell® control valves are equipped with this bell. In this case the movement of the bell is comparable to a spherical valve. The pressure drop is effected in two steps. Inlet and outlet have the same shape. Equivalent flow in both directions is possible.

b) Special-Control Bells

For specific applicatons especially adapted control bells are available.

By very fine machining of control groove in connection with 2 - stage pressure reduction, smallest KV values of 0,0001 can be controlled with an excellent resolution.


For example:

  • single stage control bell for Gas/solid application
  • Bell of Siliciumcarbid SiSiC
  • Control bell with two extremely different control ranges

Why Varibell

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.
