FAQ - Cycle Rate Regulators (Speed Control)

4-20mA or 0-10VDC Control Board. A closer look

V Series Cycle Rate Regulator board

What does a Cycle Rate Regulator do?

It slows the cycle time of the actuator down by pulsing the motor.  The standard V series control board provides five speed reduction settings from 1:1, 1:2, 1:5, 1:10 and 1:20.  The speed control option board (CRR) provides adjustments from 3 to 200 times the normal cycle time by adjusting the length of the "on " and "off" pulses.   A set of jumpers on the CRR board controls whether the "open" cycle, the "close" cycle or both are effected.

In what applications would you most likely need a Valvcon Cycle Rate Regulator?

In applications where water hammer or temperature shock is a potential problem.  The cycle rate regulator is also used to slow the open or close cycle to aid in balancing automated systems.
