Product Description

 Z series excavator hydraulic control valve

Introduction:

   The Z series multiple directional valves are several direction valves and a variety of additional safety valve and valve combination of the blocks combination valve may require a combination of parts work for even less than 10 multi-valve blocks. It has a high-pressure work, compact, good safety performance, high reliability and general good and so on. This series of multi valve is all each joint with a one-way valve. According to the needs of the user, Can be installed the overload valve and oil charge valve between the any one of the working channel and backing channel. Can be composed of parallel, serial or parallel strings oil complex, and there are a variety of sliding valve function, positioning, reduction and control methods may also make use of the bridge body to the mouth of oil or other external agencies to provide oil to meet a wide range A host of different needs.It is mainly used for the following ZL40 loader and multi-loaders, excavators, and other small-scale engineering machinery hydraulic system, also used for hoisting and conveying machinery, mining machinery, agricultural machinery or other mechanical hydraulic system, the multi - In executing agency of centralized control.

Advantage:

  Improved smooth flow way with great capacity of small pressure loss, oil, fine micro performance,easy in operation, small leakage (inner hole of high precision, high safety valve opening and closing properties.
