This 5 spool hydraulic valve is currently the standard valve body used on all Miller Rollback Car Carriers and Industrial Carriers. Sometime in 2013 this began being installed on all Miller carriers. The applicable carrier models include 10 Series, 12 Series, 16 Series, 20 Series, and 30 Series carriers. Originally designed for the Chevron brand, it is now used on all Miller brands including Chevron, Century and Vulcan.

This 5 spool V20 Gresen hydraulic valve block mounts to the subframe under the bed towards the center of the truck frame. Linkages from the sides of the body attach both the driver and passenger side controls.

If you have an older model of rollback carrier (2013 and older) where the valve body is mounted on the backside of the driver side controls use part # 12-0302179. This is a 5 spool Parker control valve.

If the bed was ordered with more than 5 functions, there are other hydraulic valve bodies currently used with 6, 8 or 9 spools.
