Control Valve Flow Characteristics - Electrical Volt

WebFlow control valves are used to regulate the flow of fluids. Control of flow in hydraulic systems is critical because the rate of movement of fluid-powered machines or actuators depends on the rate of flow of the pressurized fluid. Some of the major types of flow control valves include: Ball Valves WebWhat is Flow Coefficient (Cv)? The Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve manufacturer that describes the number of U.S. gallons that can pass through a valve (in a fully open position) at a pressure drop of 1 PSI. Webvariation across the control valve, as the control valve operates from minimum flow at its initial travel position to its maximum flow at its fully opened position.
