What is a Control Valve? A control valve is a variable orifice designed to regulate the flow of process fluids. By throttling the flow, control valves can adjust from fully open to fully closed, …

Control resolution: The valve and control package should be able to achieve the desired process control parameters, such as responsiveness, deadband, hysteresis, resolution, and other …

Introduction An Often-Asked Question: What Is a Control Valve? The simple answer is: A valve that controls the rate of flow in a piping system as commanded by a pneumatic or electronic …

A control valve creates a pressure drop in the fluid as it controls the flow rate. The profile of the fluid pressure, as it flows through the valve, is shown in the following graph.

The Figure 3 shows the flow rate diagram of a compressible fluid flowing through a valve when changing the downstream pressure under constant upstream conditions.
