      Features

      Precision casting, beautiful appearance; The structure andperformance of the pilot piston are stable. Good sealingperformance and quick switch. Autocratic coil, not easy to burn;

      Principle

      Normally closed: when the coil is energized, the electromagneticcore is attracted, the pressure relief hole is opened, the main piston. is pushed by the medium pressure, the main valve port is opened,and the medium circulates. When the coil is de energized, themain valve port is closed and the medium is cut off.Normally open: when the coil is energized, the electromagneticcore is attracted, the pressure relief hole is closed, the main pistonis pushed by the medium pressure, the main valve port is closed,and the medium is cut off.
