Regulating.Valve.Capacity
Enter the maximum flow capacity of the regulating
valve in Gallons Per Minute (GPM). The valve
parameters needed to drive the regulating valve
smoothly depend on the size of the valve.
• Use the PLUS or MINUS keys to adjust
the valve so that it matches the maximum flow
capacity (GPM) of the regulating valve being
used.
• Press the PROGRAM key to advance to the
next step.

Common Regulating Valves:
Valve GPM
344AE-2RL 27 GPM
344AE-2RB 30 GPM
344AE-2PR 12 GPM
AA346ZR 85 GPM
AA346ZRB 85 GPM
Regulating.Valve.Speed.-.Coarse.
Adjustment
This step allows for the adjustment of the pressure
regulating valve speed to accommodate different
application needs. Operating conditions may
necessitate a higher or lower response speed for the
regulating valve.
The coarse adjustment controls the speed of the
valve when large adjustments in flow are required by
the controller.
• Use the PLUS or MINUS keys to
increase or decrease the response time.
Any number between 0 - 19 can be selected.
0 = slow
19 = fast
If the regulating valve is plumbed in a bypass line,
the valve speed coarse adjustment number of “15”
works well in most applications.
If the regulating valve is plumed in the Throttling
position (supply line) start with a coarse adjustment
speed number of “5” and adjust the number
according to application requirements.
• Press the PROGRAM key to accept the
value and advance to the next step.
