The Model 590 series rotatry ball style control valve is used in all kinds of demanding applications, in oil and gas production and chemical process industries.

It is also suited to high flow, low pressure drop services. 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.

The 590 series, when combined with a Model DFRP Piston actuator, is a rugged control valve assembly, to which a wide variety of positioners and accessories can be mounted.

The Model 590 control valves is manufactured to a high level of quality specifications to ensure superior performance and customer satisfaction.
