The Bendix Spring Brake Valve Sr-7 K048634 is a spring brake modulating valve used with dual air brake systems and spring brake actuators to control parking and emergency brake functions. It provides rapid application of the spring brake actuator during parking and modulates spring brake application through the dual brake valve if the primary service brake circuit fails, while preventing compounding of service and spring forces. The valve incorporates one park control, one service control, one supply, one balance port, four delivery NPTF ports and a downward-facing exhaust port protected by an exhaust diaphragm. Key connections include 1/4-18 NPT balance, control and park control ports, four 3/8-18 NPT delivery ports and 1/2-14 NPT supply and exhaust ports. The unit mounts via two 3/8-16 UNC-3B studs and operates between -40 �F and 200 �F (-40 �C to 93 �C). With a weight of around 1.3 kg and compliance to FMVSS 121, it suits heavy vehicle brake system service and replacement.
