Borgwarner produces these products in both normally high and normally low configurations. Typical applications include actuating a multiplexing valve which in turn directs hydraulic pressure to the proper clutch. PWM solenoids, available in High-flow and Low-flow variations, provide pressure output proportionally or inversely proportionally to input voltage pulse width. The low-flow solenoid provides signal level control, typically for torque converter control. The high-flow solenoid is used in line pressure or direct clutch control applications.
