Z series multi-way directional sectional valve is a combination of directional valves, safety valves, and several auxiliary valves. It can be integrated into multi-way valve group with 10 valves at most. This hydraulic control valve shows good performance in high pressure, compact structure, great safety valve properties, and high reliability. Each joint of the valve is equipped with a one-way valve. According to users’ needs, we can mount overload valve or oil fill valve between any of the working and backing channels. The valve can be combined into parallel, serial or parallel strings oil complex. Besides, there are a variety of positioning, pressure reducing and control manners available. The valve group is able to supply oil for other structures through bridge or oil pot.
Z series hydraulic directional control valve is mainly used for the hydraulic drive system of loader over ZL40, multi-function loaders, small excavators, hoist and conveyor system, mining machinery, agricultural machinery or other machineries, to realize centralized control for various executive structures.
The inner valve body is of high smoothness, allowing for little pressure loss and large oil flow. The hydraulic valve features small leakage (high precision of inner hole), easy operation, high precision, and flexible safety valve.
