Product Description
The Bendix 800646 E-8P Dual Circuit Foot Brake Valve is a heavy-duty pneumatic control valve designed to regulate service brake application and release in commercial trucks, tractors, and other vehicles equipped with dual-circuit air brake systems. Its independent primary and secondary circuits provide graduated braking control while helping maintain braking capability if one circuit experiences a pressure loss.
Featuring integrated push-to-connect air line fittings, the 800646 simplifies installation and eliminates the need for separate threaded adapters on its primary supply and delivery connections. The valve incorporates a rubber graduation spring and a 3 PSI differential pressure specification to provide smooth, responsive braking control.
Built for demanding commercial vehicle environments, this genuine Bendix replacement valve is supplied as the basic E-8P valve assembly without the foot pedal, mounting plate, or rubber boot.
