4.1 Prior to applying supply pressure to the booster, open the bypass valve approximately one turn by turning
counter clockwise. After applying supply pressure, note response of actuator to open and close
commands from the positioner. If excessive overshoot or hunting is seen, open bypass valve until stable
operation is obtained. If valve becomes too slow to react to signal change from the positioner, close
needle valve until more responsive.
Turning the bypass valve clockwise (closing) speeds response but can lead to instability. Turning the
bypass valve counter clockwise (opening) aids stability but will slow down the actuator’s response. Proper
setting provides stable operation and acceptable response time.
Under normal circumstances, no maintenance should be required.
