This valve is a two‑position three‑way directional control valve. It is used in conjunction with the reverse‑modulating hydraulic brake valve. It realizes service‑brake and parking‑brake functions by connecting or cutting off the oil circuit. The lever is equipped with a self‑locking feature at both the service‑brake and parking‑brake positions to prevent mis‑operation.
