Rotary globe control valves have good rangeability, repeatability
control, and are capable of tight shutoff . Unlike normal globe
valves the V-port provides high capacity, precise control across a
broad range of applications because of the V-slot machined into
the ball. These also provided a non-clogging, high capacity flow
control. The actuator/positioner/valve linkage are enclosed for
both personnel safety and protection against damage.
