The PAI EM34590 is a modulating valve identified as R7 with 95 psig spring brake release pressure, one 1/4-inch control port, one 1/4-inch-18 balance port, and two 3/8-inch-18 delivery ports. As heavy duty diesel truck parts, modulating valves regulate pneumatic signals and route air within a vehicle's braking system, while the listed pressure and port configuration provide important details for matching the component to the required air-circuit layout.
