Model 590 full ball style control valves are used in all kinds of demanding applications, oil and gas production and chemical process industries. It is also suited to high flow, low pressure drop service. The 590 series is used in both throttling and on/off control of liquids or gases.
The straight through unrestricted flow path provides higher capacity than globe style valves. A splined shaft provides accurate control in throttling operations and flexibility in actuation options.
