Flow Control Valve general-purpose control valves are used for throttling or on-off control of a wide variety of liquids and gases. valve designs have single ports, balanced valve plugs, and cage guiding.Metal-to-PTFE seating for stringent shutoff requirements is standard in all valves.The temperature limits are extended to 316°C (600°F) for non-oxidizing service and to 260°C (500°F) for oxidizing service.Different cage/plug styles that provide particular flow characteristics for highly-specialized applications. The standard cage comes in three different flow characteristics: ■ quick-opening, ■ linear ■ equal percentage.

Smart Positioner is a HART® communicating instrument that converts a two−wire 4−20 mA control signal into a pneumatic output to an actuator. It can easily be retrofitted in analog positioners and pneumatic actuators.
