The six way multiple valve continue to exist

Although the load sensing system using four way valve to provide accurate operation, but not all occasions needprecise operation, and skilled drivers can complete precise operation non load sensing system for excavator. More important is, the higher price of load sensing system, limit its application in developing countries. At present, many of the world's famous excavator manufacturers, their products in both load sensing control excavator using four valve,also use the six way valve hydraulic system such as negative control, positive rate of excavator. Mature manufacturing technology and low prices will make the six way multiple valve continues to play a role.
