Ball valves designed for control of hot, cold or glycol-mixed water in heating and ventilation systems. These ball valves can be used as either characterized control ball valves when a flow plate is installed in port A (default mode), or as on/off ball valves when the flow plate is removed. When the flow plate is removed the Kvs between port A and AB is increased. The valves are intended Manual control: The manual control is used to open the valve without supplying voltage to the coil. The control consists of a slotted-head screw for a screwdriver with two possible positions: CLOSED (valve closed) if letter "C" is tur ned upside (fig. 1). OPEN (valve open) if the letter "A" is turned upside (fig. 2). The below CV values are used to give an indication of flow rates for ball valves. CV value is an imperial measure of flow in US gallons per minute of water at 60° fahrenheit with a pressure drop of 1 psi across the valve. This is used as a guide and is not a linear progression.
