Poor Performance - Steps in Control. Example of poorly performing pwm control valve. Curves have large
control steps, which will result in unresponsive control and poor system performance. PWM control valve may
need to be cleaned or replaced.
Poor Performance - Narrow Control Range. Example of very narrow pwm valve control range. Pressure reaches
maximum in a very narrow Control Effort Duty Cycle % range (<20% overall range). Target Rate, Pressure,
Speed, and Tip selection must be carefully chosen to ensure control is adequate. Increasing agitation may help
in some cases if possible.
