Product Overview | Control Globe Valves
AGENCY APPROVAL
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.
