Bendix K079665 M-40HF ABS Modulator Valve 12V – High Flow
The Bendix K079665 M-40HF ABS Modulator Valve is a heavy-duty pneumatic braking component designed to regulate air pressure in commercial vehicle antilock braking systems (ABS). This high-flow valve helps provide precise brake pressure modulation, improving vehicle stability and control during demanding braking conditions.
The M-40HF modulator works with the vehicle's ABS electronic control unit to rapidly adjust air pressure delivered to the brake chambers. During an ABS event, the valve can hold, release or reapply brake pressure as directed by the control system, helping prevent wheel lockup and maintain traction on slippery or uneven road surfaces.
Designed for dependable performance in demanding commercial truck environments, the Bendix K079665 features a 12-volt electrical system, 150 PSI maximum operating pressure and a circular DIN three-way twist-lock electrical connector. Its high-flow design supports responsive air delivery and controlled braking performance.
The durable construction and compact design make this valve suitable for maintaining or repairing compatible heavy-duty truck ABS systems.
