Electromagnetism Cross Valve
In addition, the differences between the electromagnetism cross valve and the proportion valve lies in the valve spool structure.
Proportional Valve
By changing the coil electric current, the distance of the valve core can be changed, thus the discharge flow rate of the proportion valve is under control.
Proportional Valve
However, the proportion direction valve can be controlled by the electric installation which is similar with adjustive switch of the luminosity.

Switch The Electromagnetism Cross Valve
The electromagnetic directional valve may be considered as the simple switch valve. It may be controlled by the electric installation, which can put through or shut off the electric current.
