This SURE-FLO aluminum foot valve is for use on hose, pipe or plastic pipe. The durable rubber flapper seats on a machined aluminum surface and provides a tight seal which minimizes leakage. Unlike the old fashioned leather flapper it does not dry out or shrink when out of service. Ample space is provided for the flapper to fold back out of the liquid stream thus keeping friction loss to a minimum. The hump on the body must face up when it is used in a horizontal or near horizontal position.
