Pressure switch for dual line system
The pressure switch is fixed at the end of the system (before the last blocks).
It used to detect the pressure difference between the out and back pipes.
When the difference reaches 5Mpa, the pressure switch will send the signal to the control unit.
The 2/4 way changed valve will work, the original out pipe will changed back pipe to lubrie
another side.
