Foot valve

Note) At the self-suctorial head spec, be sure to add a foot valve to the suction pipe. Install the suction-side foot valve upright a little above the bottom inside the tank in order not to suck in sediment.

Check valve

Note) When the check valve is to stand at the injection point, install it upright from below in order to improve the sealing effect with the ball weight of the check valve and the injection side pressure.
