What is the function of the balance valve of the filter? When should it be opened? When is it closed?

The balance valve balances the pressure between the left and right barrels. The valve with a shut-off orifice is normally open (closed after the switch is completed, and opened after the filter element is replaced), and the one without a shut-off orifice is normally closed (open when the switch is switched, and close after the switch is completed ), in order to reduce the disturbance of the oil flow, the balance valve of the current filter adopts a shut-off orifice plate.
