PDF09 Reverse‑Modulating Parking Brake Valve
This reverse‑modulating parking brake valve adopts the principle of a direct‑acting three‑way pressure‑reducing valve. Parking braking is achieved when used with spring‑applied / hydraulically‑released brakes. It integrates maximum pressure limitation for brake‑release pressure, delivering precise control and favorable mechanical operability. The lever features a self‑locking function at the parking position to prevent mis‑operation.
