Water Control ValveWater Control Valve are designed to handle and control hot water, cold water, ground water, potable water, salt water and/or wastewater. They are made from metal or plastic. Metal water valves are made of aluminum, brass, bronze, cast iron, ductile iron, copper, steel, or stainless steel. Selecting water valves requires an analysis of performance specifications, actuation methods, and connection types. Performance specifications include valve size, pressure rating, number of ports or ways, media temperature, and valve flow coefficient. Suppliers specify valves according to metric or English (imperial) measurements. Some Water Control Valve are actuated manually, by a hand wheel or crank, or with mechanical devices such floats and cams. Others are actuated by electric, pneumatic, electro-hydraulic, or electro-hydraulic methods. There are many connection types for water valves. Examples include compression fittings, bolt flanges, clamp flanges, union connections, tube fittings, butt welds, and socket welds. Water valves with internal or external threads for inlet or outlet connections are also available.
