SR-2 Trailer Control Spring Brake Valve - 3/4 Inch NPT Reservoir w/o Service Port.

This is an SR-2 model spring brake valve. The SR-2 valve controls the function of the spring brakes on a trailer air brake system during parking and emergency applications. It can automatically apply the spring brakes and prevent trailer air pressure loss in case of breakaway or supply line failure. It also avoids the automatic application of the trailer spring brakes after the loss of trailer service reservoir pressure while allowing failure indication to occur on the tractor. The SR-2 is used on trailers with dual air brake systems. It also provides the ability to release the spring brakes at least once prior to their application. .
OEM Part # 287376

Technical Specifications:

  1. Limits hold-off pressure to the spring brakes through a quick release relay valve (generally 90-95 PSI).
