Solenoid valve control system

摘要

A solenoid valve that includes a valve body in which a valve spool is slidably mounted, and a solenoid assembly mounted at one end of the valve body. The solenoid assembly includes a solenoid having a plunger operatively coupled to the spool and a solenoid coil for actuating the plunger. A solenoid valve driver circuit includes a circuitboard assembly that has a power supply responsive to external power for supplying electrical power to the driver circuit and the solenoid coil, and a microprocessor-based control circuit responsive to external control signals for controlling actuation of the solenoid coil. The solenoid assembly, including the solenoid and the circuitboard assembly, comprises a unitary molded or potted assembly.
