The Midland Haldex proportioning valve, part number 90054170, lets a single height control valve operate two suspensions that require different air pressures. All ports are 1/4" NPT, and the output is adjustable ±30% around a separate control signal, giving technicians the flexibility to fine-tune pressure balance between circuits. This valve is commonly applied in specialty vehicles where a tag or pusher axle system runs at a lower capacity than the primary suspension, or in coil spring lift installations that need elevated pressure to overcome spring resistance. Call us to confirm proper fit for your application.
