Description

Overview

The R-7 modulating spring brake valve is a safety critical part in heavy truck and trailer air brake systems, and the SCTEG R-7 modulating spring brake valve gives controlled spring brake hold off and emergency application when rear service pressure is lost.

Features

• R-7 style modulating valve for dual circuit air brake systems on heavy vehicles
• 95 PSI spring brake release pressure matched to common Bendix R-7 applications
• Two 3/8 NPT delivery ports plus 3/8 NPT supply, 1/4 NPT control and 1/4 NPT balance ports
• Compact body that suits chassis or crossmember mounting in crowded air brake layouts

Specifications and Materials

Part number: AB8345.
The SCTEG R-7 modulating spring brake valve matches typical Bendix R-7 technical attributes including dual 3/8 NPT delivery ports, 3/8 NPT supply port, 1/4 NPT control port, 1/4 NPT balance port and a nominal 95 PSI spring brake hold off pressure. Additionally, the housing uses a robust cast body with a corrosion resistant finish to cope with road grime and moisture.

After installation, confirm plumbing against the original valve so supply, control, balance and delivery ports line up correctly.

Compliance and Safety

Spring brake valves sit at the heart of the parking and emergency brake system, so they must be installed and tested carefully. Finally, always depressurise the air system before removal, then torque fittings to the correct values and check for leaks with soapy water once the system is charged.

Trailer Applications

This R-7 modulating spring brake control valve suits many prime movers, rigid trucks and trailer installations that use R-7 style spring brake circuits. Consequently, it is commonly used in linehaul, regional freight and vocational applications where controlled spring brake modulation is required during an emergency stop.
