The JPDF18 series parking brake valve employs a two-position, three-way directional control valve principle. When paired with a reverse-acting hydraulic control valve, it enables both normal vehicle operation and parking functions by connecting or disconnecting hydraulic circuits. Its operating handle resembles an automotive parking brake lever, featuring a self-locking mechanism in the parking position to prevent accidental operation. This design combines aesthetic appeal with practical functionality.
