Wide rangeability and stability
Control valve rangeability is the ratio of maximum controllable flow to minimum controllable
flow. The Habonim ball valve has an inherently high flow ratio of 1:50..
This unique advantage allows diverse process parameters with the same control unit. However,
optimum flow control through the valve is achieved within the 20-80% range of rotation
because the hydraulic flow curve is unstable outside the limits of this range.
The Habonim design offers exceptionally wide rangeability with maximum stability of process
conditions.
High recovery
A high recovery valve is designed with streamlined internal contours and minimal flow
turbulence that dissipates relatively little flow stream energy. Therefore pressure downstream
of the valve’s vena contracta recovers to a high percentage of its inlet value.
The streamlined interior design of the Habonim valve dissipates little energy, resulting in
higher recovery and a more cost efficient flow process, especially when compared with the
tortuous flow globe valve.
