PART NUMBER(S):
Fleet Products: 101622-G | Replaces OE: Bendix: 101622, 108076 | Automann: 170.101622 | WABCO: 9738840010 | Mack: 745-101622 | Meritor: R955101622 | PAI: EM56630
DESCRIPTION:
Model: Bendix SR-4 Style Trailer Spring Brake Valve with Anti-Compounding
Vehicles: Single- and tandem-axle trailers using compatible spring brake systems
• Valve Type: Pneumatic trailer spring brake control valve
• Supply Port: One 1/4" NPT
• Service Port: One 1/4" NPT
• Delivery Ports: Four 3/8" NPT
• Primary Reservoir Port: One 1/2" NPT
• Additional Reservoir Ports: Two 1/4" NPT
• Exhaust Port: One 3/8" NPT
• Spring Brake Release: Uses service reservoir pressure to release the trailer spring brakes
• Anti-Compounding: Prevents simultaneous full service and spring brake application
• Pressure Protection: Integrated check-valve and pressure-protection functions help isolate reservoir pressure loss
• Function: Controls trailer parking and emergency spring brake application and release
Applications:
Designed for trailer air brake systems requiring integrated parking brake control, emergency spring brake application, reservoir pressure protection, and anti-compounding. It is typically replaced when the spring brakes release slowly, fail to apply after trailer 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 and service, four 3/8" delivery, 1/2" primary reservoir, two 1/4" reservoir, and 3/8" exhaust connections.
✔ Verify the mounting position and reservoir plumbing match the original SR-4 valve configuration.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve passages.
✔ Keep the exhaust port and dust shield clear of contamination or obstruction.
✔ Pressurize and leak-test the system, then verify spring brake release, emergency application, pressure protection, and anti-compounding.
