The HBS 2-Wire hydraulic solenoid valve (054-140-22) is a must-have for trailer brake systems, enabling automatic free-backing when reversing—no need for manual switches. This reverse lockout solenoid works seamlessly with Dexter, Titan, and Dico disc brakes, as well as Germany’s Knott systems.
This is a hydraulic solenoid valve for trailer, the voltage is 8 W, 12 V DC. Both 1-wire and 2-wire are available, the essence is the same, the only difference is the wiring, some can be connected with one wire, some need to connect 2 wires. The letter IN is the oil inlet, the letter OUT is the oil outlet when the hydraulic solenoid is powered on, and there is also an internal thread interface for the DC port.
