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...

Internally piloted solenoid valves are fitted with either a 2- or 3-way pilot solenoid valve. A diaphragm or a piston provides the seal for the main valve seat. The operation of such a valve is indicated in Fig. 4. When the pilot valve is closed, the fluid pressure builds up on both...

The Cv of the valve will determine how much flow is required to create a 5 psi differential across the valve. What happens to the valve when the actual flow is below that value, resulting in a greatly reduced pressure diff? ... like, 0.1 psi. Does anyone work with pilot operated sole...
