Description

Overview

This E6 dual foot brake valve controls the primary and secondary service brakes on heavy trucks and trailers. It mounts on the cab floor under the treadle and gives the driver graduated air pressure as they press the pedal. Consequently, brake applications stay smooth and predictable in both loaded and empty conditions.

Features

• Dual circuit layout separating primary and secondary service brake feeds
• Floor mounted, treadle operated design for intuitive pedal feel
• Porting pattern that follows common E6 dual foot brake valve schematics
• Robust body and internal components suited to heavy vehicle service

Specifications and Materials

Part number: AB8347P.
This E6 dual foot brake valve is a floor mounted, treadle operated control valve with two independent supply and delivery circuits for service braking. It uses inlet and exhaust valving to build delivery pressure in proportion to pedal travel, then vents the circuits cleanly when the driver releases the treadle. Additionally, the port layout supports separate plumbing of front and rear axle circuits, which helps maintain braking balance if one circuit loses supply. For detailed technical information on operation and port configuration, refer to the Bendix E-6 dual brake valve service data sheet which explains the original valve design and service procedures.

Compatibility and Fitment

This valve suits heavy vehicles and trailers that specify an E6 or E-6 type dual circuit foot brake valve in the air brake schematic. This cross-reference listing means this valve is a suitable replacement for the part numbers and applications shown. Some changes in air line plumbing may be required.

Compliance and Safety

Always follow the vehicle manufacturer’s drawings and recognised heavy vehicle air brake practices when replacing an E6 dual foot valve. Firstly, isolate the vehicle, chock wheels and fully drain air reservoirs before loosening any lines. Then install the valve so that supply and delivery ports match the original plumbing, using new thread seal where specified. After installation, leak test every joint, confirm both circuits build pressure correctly and verify that pedal movement produces proportional brake response at all axles.

Trailer Applications

Fleets use this style of dual foot brake valve on prime movers, rigid trucks and trailer combinations with full air brake systems. The SCTEG E6 dual foot brake valve suits linehaul, distribution and tipper work where drivers need consistent pedal feel in varied load conditions. Additionally, it supports mixed combinations where reliable control of both primary and secondary circuits protects trailers and dollies across the set.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

In addition, technicians should still confirm port sizes and mounting to match the original installation on the specific truck or trailer.
