Hydraulic valves are controlled pneumatically with three parameters of pressure. Valve is extremely essential in multi-function systems (eg. the tipping-lorry with the crane and the drive to fuel tank). The saddle-tractor equipped with such system becomes more universal. This distributor is quipped in manageable valve giving the possibility to stop the loading-box at any position and the proportional valve which cooperates with pneumatic driver giving the possibility of smooth abandonment of the loading-box even at incomplite unload.
Three road-valve controlled manually can work with pressure up to 350 beriums. It is possible to switch the stream of oil from the car to trailer.
Three road-valve controlled pneumatically and hydraulically.
