Edstrom Hog Valves

The Edstrom Hog valves have a 5 year warranty and are manufactured with 303 stainless steel for even longer life. There is no spring to break or screen to clog, but rather a silicone diaphragm works against the head of the valve stem to control the water flow. The tension of the retaining screw allows for some adjustment of water flow volume. This design gives a fairly consistent water flow across all water pressures. A lower water pressure will result in less water wastage and still allow the livestock to get sufficient water.
