Midland Air Brake Valves
These Are New Midland Air Brake Valves. No core charge!
We can help you identify your Midland / Haldex brake valve if you cannot find it below. The part numbers begin with 'KN', but many times you will find what is referred to as the OEM number on the valve. It begins with a 'N'. Once you find the OEM number on your valve, you can use the excellent cross reference program at the Haldex website to get the current 'KN' part number. Contact us if you can't find that number on our site. We're a Haldex distributor, so we can have any valve not in our inventory shipped directly from Haldex to you.
The valves below are separated into their basic types and then listed numerically by part number. Click on the part number for detailed valve information and to purchase the valve.
