The Midland Haldex KN31050 is an adjustable air regulating valve designed specifically for auxiliary air systems on heavy-duty trucks. It is not intended for brake system use. The valve features 1/4" NPT inlet and outlet connections with a factory pressure setting of 45 PSI, based on a 100 PSI supply. It is designed for constant-supply applications, not on-off cycling. Where a reduced, steady air pressure level is needed in an auxiliary circuit, this valve delivers controlled output. Call us to confirm proper fit for your application.
