1.Introduction：

    The 23QDF6 and 24QDF6 solenoid ball valves are used in 2-way cartridge valve assemblies with minerals as working medium, to realize pilot control of leaks. While satisfying the need of pressure drop and flow control, they may also serve to control the directions of other actuators.

  The W23QDF6 and W24QDF6 ball type solenoid reversing valves are manufactured using anticorrosive material and special workmanship, hence suitable for working with non-mineral oil mediums such as emulsified liquid, high-water-based hydraulic oil, and even suitable for working in pneumatic control units.
