RV‑Series Relay Valve
This valve is a direct‑acting proportional pressure‑reducing valve with hydraulic pilot control. Its output pressure is proportional to the pilot pressure. It is applied in systems with long brake pipelines or large‑volume brakes. Mounted close to the brakes, it effectively improves the response speed of the brake system.
