HPV-Controller is an el-operated priority valve, which via 1 double acting oil outlet on the tractor can control up to 4 double acting functions on the machine, by which the demand on the number of outlets on the tractor is reduced. If 2 or more functions are to be activated simultaneously, this is possible by activating the el-switches in question, and the tractor´s oil outlet then activates all functions at the same time - e.g. markers together with lifting of a trailed machine. HPV-Controller is available for mounting on new HE-VA machines or as a standard set (not adapted) for retro mounting on all types of machines.
