Solenoid pinch valve apparatus and method for medical fluid applications having reduced noise production |
摘要 |
A low noise solenoid valve system includes a solenoid valve; and a controller configured to perform a power actuation sequence in which power to the solenoid valve undergoes a plurality of cycles that switch from an actuation level power to a hold level power, wherein the actuation level power is increased at each subsequent cycle, and wherein the actuation power level of one of the plurality of cycles is sufficient to fully actuate the solenoid valve. |
