Vertical OD Tubing Foot Valve is made out of lightweight and durable aluminum.
Ample space is provided for the valve flapper to get out of the water stream, and the full size opening means minimum friction loss.
Especially suitable where the aluminum tubing used for suction is to be in a vertical position.
However, this foot valve will also work where the tubing is at an angle or in the horizontal position.
The hump on the body must face up when it is used in a horizontal or near horizontal position.
Note: Every valve will leak if there is no head pressure pushing down and sealing the flapper. Head pressure comes from the vertical down pressure of the volume of water above the valve. The weight of the 4 vertical feet of head pressure will push down and seal the valve. Below is a diagram showing how to measure the four feet of vertical lift from the water surface up to the centerline of the pump.
