speed for the regulating valve. This value sets the speed for coarse adjustments in relation to a large percentage
outside of the target application rate
►If the system is too slow in finding the correct rate, the values should be increased.
►If the system is too unstable, the values should be decreased.
• To select the Valve Calibration, Rough, use the number pad or slide bar.
If your system is plumbed in a bypass mode, the valve speed number of 9 works very well in most applications
If your system is plumbed in a throttling mode, start with a valve speed number of 3 and adjust the number
according to your application requirements. Low fl ow situations will require a slower response time. Adjusting
agitation volumes to accommodate the regulating valve to work in a more fully open position allows for a faster
response time, with little to no searching.
NOTE: This speed value can be adjusted to optimize system performance. If you notice that the valve seems to
“search” for the programmed application rate by cycling the pressure up and down continuously, reduce
the number until the “searching” is minimized or eliminated. Conversely, a higher number will increase the
valve response speed and speed up the rate of adjustment.
Valve Calibration, Fine
Fine regulation value calibration allows you to regulate the speed of the pressure regulating valve to
accommodate different application needs. Operating conditions may necessitate a higher or lower response
speed for the regulating valve. This digit sets the speed for the fi ne tune adjustment in relation to a small
percentage close to the target application rate.
►If the system is too slow in finding the correct rate, the values should be increased.
►If the system is too unstable, the values should be decreased.
• To select the Valve Calibration, Fine, use the number pad or slide bar.
If your system is plumbed in a bypass mode, the valve speed number of 5 works very well in most applications.
If your system is plumbed in a throttling mode, start with a valve speed number of 3 and adjust the number
according to your application requirements. Low flow situations will require a slower response time. Adjusting
agitation volumes to accommodate the regulating valve to work in a more fully open position allows for a faster
response time, with little to no searching.
