DESCRIPTION:
Model: Bendix R-7 / SR-7 Pressure-Modulating Spring Brake Valve
Vehicles: Heavy-duty trucks, tractors, and buses using compatible spring brake modulation systems
• Valve Type: Pressure-modulating spring brake valve
• Supply Port: One 3/8" NPT
• Delivery Ports: Two 3/8" NPT
• Control Port: One 1/4" NPT
• Balance Port: One 1/4" NPT
• Release Pressure: 95 PSI
• Actuation: Pneumatic, foot-valve controlled
• Mounting: Standard flange mount
• Body Material: Metal
• Function: Modulates spring brakes after rear service brake failure
• Configuration: Dual-delivery, fail-safe design
Applications:
Designed for heavy-duty air brake systems requiring controlled spring brake application following a rear service brake circuit failure. The valve uses foot-valve pressure to modulate the spring brakes, helping maintain controlled braking rather than applying the spring brakes at full force.

A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Confirm the 3/8" supply, two 3/8" delivery, 1/4" control, and 1/4" balance connections.
✔ Mount securely using the standard flange configuration.
✔ Route the control and balance lines according to the vehicle air brake schematic.
✔ Apply air-system-compatible sealant without allowing sealant inside the valve.
✔ Pressurize the system and verify 95 PSI release pressure, modulation, and leak-free operation.
