DESCRIPTION:
Model: Bendix SR-5 Trailer Spring Brake Control Valve with Anti-Compounding
Vehicles: Single- and tandem-axle trailers using compatible dual-circuit air brake and spring brake systems
• Valve Type: Pneumatic trailer spring brake control valve
• Supply Port: One 1/4" NPT
• Delivery Ports: Four 3/8" NPT
• Reservoir Port: One 1/2" NPT
• Service Ports: Two 1/4" NPT
• Exhaust Port: Integrated exhaust with protective dust shield
• Rated Closing Pressure: 70 PSI
• Operating Temperature: -40°F to 200°F (-40°C to 93°C)
• Anti-Compounding: Prevents simultaneous full service and spring brake application
• Emergency Function: Applies the trailer spring brakes when trailer supply pressure is lost
• System Configuration: Supports compatible single-reservoir trailer spring brake systems
• Brake Capacity: Controls air delivery to as many as four spring brake actuators
Applications:
Designed for commercial trailer air brake systems requiring parking brake control, emergency spring brake application, and anti-compounding through one SR-5 valve. It is typically replaced when spring brakes release slowly, fail to apply after supply-pressure loss, compound during service braking, or the valve develops internal or external air leakage.

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 1/4" supply, four 3/8" delivery, 1/2" reservoir, and two 1/4" service connections.
✔ Mount the valve in the original orientation with the exhaust and dust shield positioned correctly.
✔ Connect the trailer service signal correctly to maintain anti-compounding operation.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve ports.
✔ Pressurize and leak-test the system, then verify spring brake release, emergency application, and anti-compounding.
