Description
The Schneider Electric (Barber Colman) VK-7211-201-3-6 Union Angle Valve offers controlled flow of water in hydronic piping systems of HVAC units. Designed as a normally open valve with a 3/4 inch union angle connection, 8.5 Cv flow coefficient and 3-7 PSI spring range, it is actuated by pneumatic action that adjusts the internal stem position to change the flow of water depending on different control air pressures. It is installed in either the supply or the return lines that supply air handlers and fan coil units and controls the flow of heating or cooling water at constant temperatures.
