Foot Valve

Note) In the case of the suction type specification, please install a foot valve. When installing the foot valve, position it slightly above the bottom surface of the tank or similar, and install it vertically to prevent drawing in sediment.

Check Valve

Note) When attaching at the injection point, please install it vertically from the bottom so that the sealing effect is improved by the weight of the check valve ball and the pressure on the injection side.
