Today’s systems demand ultimate performance from all components in the system. These include not only the primary instruments, but also the final control element, an integral part of the control loop. To meet these demands the actuator positioning the final control element must provide true proportional control in response to a signal regardless of the stem load and stuffing box friction. Without precise actuator positioning, the critical function of the final control element is reduced.
As Instrument Signal Increases, Actuator Stem:
- GJ2230: Extends
- GJ2103, GJ2215: Retracts
Stem Position On Air Failure: Can be piped to Extend or Retract. Specify When Ordering
