Designed for heavy‑duty air suspension systems, this mechanical ride-height control valve uses a lever actuator to regulate air flow to the suspension bellows based on load. Operating at pressures up to 10 bar and temperatures from –40 °C to +80 °C, it ensures reliable performance in extreme environments. The adjustable lever provides ±50° actuation for precise height control, while mounting holes spaced 40 mm apart and a 200 mm lever length simplify installation. Built without a one-way valve, the WABCO 4640080110 maintains stable suspension alignment and helps prevent chassis sag under varying loads.
