Beiye NJ136 Relay Valve Assembly

This pneumatic relay valve functions as a remote air control station within the heavy vehicle braking system. It receives a control signal from the brake pedal valve and directs high-volume reservoir air directly to the brake chambers, reducing lag time for brake application and release. The valve body is constructed from die-cast aluminum alloy with corrosion-resistant surface treatment. Internal components include a reinforced diaphragm, return spring, and precision-machined spool assembly calibrated for standard commercial vehicle operating pressures. Port threads conform to metric standards typical for Chinese commercial vehicle platforms. This unit serves as a direct replacement for the original equipment valve installed on Yuejin NJ136 chassis.
