Valve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. 阀门流量系数(Cv)是指液体或气体流过阀门的能力。 It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of ...
It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.” In simpler terms, the larger the opening in a valve, the larger the Cv. As a valve is opening, the Cv increase...
For those of you who skipped the earlier section, the equation for calculating the valve flow coefficient isCv = Q√(SG / ΔP). Now that we’ve ascertained the values for our variables, we can plug them into the equation. Once we do that, our example should look like this: Cv = 10...
Control valveCV refers to the flow coefficient of the valve. It applies to the factor of the head drop (Δh) or pressure drop (ΔP) over a valve with the flow rate Q. Calculating Control Valve CV When Sizing (calculating which size valve is needed for your application ) a control valv...
atmospheric pressure, is connected to the inlet port P. FLOW RATE VALUES The flow rate through a valve is determined by the nature of the design and by the type of flow. The size of valve required for a particular application is generally established by the Cv rating. This figure is ...

The flow control valves are used for controlling and adjusting the fluid or gas flow through the system. The pressure control valve is used to regulate the pressure of a fluid passing through the pipe.
