The Wabco 975-303-060-0 or 9753030600 unloading valve is an air system valve with a one way valve, built without a tire inflating valve. An unloading valve regulates air pressure in the circuit and relieves pressure at the point it is set to, so braking stays consistent. Cut-out pressure is 117.48 psi and opening pressure is 174 psi, with a maximum operating pressure of 362.6 psi. Ports are M22 x 1.5 and M12 x 1.5, with a 0.79 in union at port 3, and the valve mounts on 2x 8.8 mm holes. A genuine Wabco part from Pro Gear and Transmission. Call us to confirm proper fit.
