Introduction

The 3518010‑431 Relay Valve is a key pneumatic control component of the FAW heavy‑duty truck air‑brake system. It accelerates air charging and exhaust for brake chambers, shortens brake response time and realizes fast and reliable braking for trailer and driving axle. Working under high‑pressure air‑circuit conditions for long periods, this relay valve adopts precision internal valve core structure and high‑quality sealing components. It effectively solves common brake‑system troubles such as slow brake response, delayed release, insufficient braking force and air leakage caused by aging or damaged original relay valve. It guarantees stable and reliable braking performance under heavy‑load transportation, downhill and emergency‑braking conditions, and serves as a critical OEM replacement spare part for FAW truck brake system maintenance and overhaul.
