Setting the Valve Flow Adjuster
The flow setting may only be adjusted if the 0.375 and 0.75 inch port sizes are installed and only when using the on/off
version.
When shipped from the factory, the actuator has the flow adjuster set at the maximum flow rate position for the given
port size.
1. Ensure the valve plug is in the seated position.
2. To change the valve flow rate, loosen the flow adjuster socket head cap screws (key 15) with a 5/32 inch Allen key,
and reposition the flow adjuster halves (key 13 and 14) to the desired flow rate position. See figure 19 for flow rate
settings.
3. Retighten the socket head screws (key 15) to 3 NSm (26 lbfSin).
4. Follow instructions for recalibration on page 10.
