Anderson Patent Altitude Valve.
A unique yet essentially efficient and practical device is the Anderson patent cushioned controlling altitude valve which is fully described and illustrated in the Golden-Anderson Valve Specialty Company’s new catalogue, No. 12. The purpose of this valve is to do away with the annoyance of floats in reservoirs, tanks and standpipes as a means of indicating the stage of the water in the same, and also to relieve those having such tanks or standpipes in charge from the task of constantly watching the float indicators. In short, the valve substitutes an infallible automatic arrangement a large degree surer in its results than fallible human attention. The Anderson valve may be operated in three ways; Automatically, by the back water pressure from the reservoir, or by electric control from superintendent’s office, pumping station or other desired place, even though miles away, and. also, if desired, the valve may be controlled by hand. The valves are most positive in their action and the air cushioning provision eliminates the pattering and hammering when subjected to the closing pressure. The upper part of the valve body into which the hollow piston recedes when the valve is open is of bronze and the piston is bronze also, and is fitted with rubber cups and disks preventing metal parts coming in contact. Not t only do these valves meet their special functions satisfactorily but also with respect to ordinary valve requirements their design insures them to be thoroughly dependable.
