Control valve bench set
WebAn actuator bench-set is the instrument air pressure required to begin moving the stem against its closure spring and to fully stroke the actuator over its entire range. These settings are applied by adjusting the spring compression to compensate for the process pressures that will act on the plug area. WebIf sequenced as such, the I/P transducer calibration and valve bench-set values may be standard rather than customized. Of course, just because the controller is capable of performing the necessary sequencing doesn’t …
