CONTROL VALVES
Less stem seal wear
The Habonim quarter-turn ball valve operation is far less prone to leakage due to resilient
seat and seal designs that deliver tighter shut-off, and a stem sealing that requires less torque
output from the actuator. This translates into longer lasting, continuous valve operation with
minimum upkeep. The rotary movement of Habonim’s valves make them safe and simple
to automate and they are ideal for flow control operations. In contrast, linear- movement
globe valves have a tendency to seize up, are susceptible to blockages, and require constant
maintenance to deal with stem leakage problems.
The Habonim valve is fitted with specially designed packing configurations. A variety of
packing materials are available to meet the needs of demanding control applications
including aggressive media, extreme temperature, and pressure conditions that range from
deep vacuum to high pressure. The end result is a high-endurance control valve assembly
that is more cost-effective and maintenance-friendly than any other type of actuated valve.
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.
