Product Description
The Bendix 800970 E-7 Dual-Circuit Foot Brake Valve is a heavy-duty pneumatic braking component designed to control service brake application in commercial trucks and other vehicles equipped with dual-circuit air brake systems. Featuring a factory-installed manifold and mounting plate, this valve provides a replacement solution for certain discontinued Bendix E-14 foot brake valve configurations.
The E-7 foot brake valve operates through two separate air supply and delivery circuits, allowing the driver to regulate braking pressure through the vehicle's brake pedal. The primary circuit responds directly to pedal movement, while the secondary circuit operates through pneumatic control from the primary circuit. If the primary circuit loses air pressure, the valve incorporates a mechanical backup function to help maintain secondary braking capability.
Designed for firewall-mounted installations, the Bendix 800970 combines reliable dual-circuit braking performance with a durable valve body, protective exhaust shield, and integrated manifold connections.

The Bendix 800970 is designed as a replacement for certain discontinued Bendix E-14 brake valves, including part numbers 065395 and 108682. Its dual-circuit construction helps maintain consistent service brake operation while providing a mechanical backup function when the primary supply circuit is compromised.
Unlike many standard E-7 foot brake valve assemblies, the 800970 includes both the firewall mounting plate and engine-side manifold, making it particularly useful for compatible E-14 replacement installations.
Common cross-reference numbers include Bendix 065395, 108682, 289352N, Ford F2HT-2A270-AA, and 3098648.
Before ordering, verify the original valve part number, firewall mounting configuration, air port arrangement, and manifold connections. Some replacement installations may require modifications to the existing air line plumbing.
The Bendix 800970 is supplied without the brake pedal or rubber protective boot. Inspect the existing pedal assembly and related hardware before installation.
