Bulldozer quick drop valve KJV20

Technical characteristics

When the blade is rising, the slide valve in the quick droop valve is maintained in the original state, and the oil enters the lifter cylinder through the quick droop valve, satisfying the rising condition of the blade；

When the blade drops slowly, the pressure loss is small, and the slide valve in the fast-dropping valve is maintained in the original state. The oil of the lifting cylinder is returned to the oil from a single loop, which satisfies the condition of slow falling of the blade                          

When the blade is in rapid fall, the pressure loss is large, which overcomes the spring force, and the shunt opening of the slide valve satisfies the condition of rapid fall of the blade；
