PDF18 Parking Brake Valve
This is a two‑position three‑way directional control valve, used in conjunction with a reverse‑adjusting hydraulic control valve. It enables normal vehicle travel and parking functions by connecting or cutting off the oil circuit. Its operating handle is similar to the parking handbrake of an automobile. A self‑locking mechanism is fitted at the parking position to prevent mis‑operation, combining good appearance with practical performance.
