How do you calculate the flow rate of a valve CV?

Control Valve SizingControl Valve Sizing. When sizing a control valve, the most common approach is to calculate the flow coefficient, Cv which is a measure of the capacity of the valve body and trim. C = Q/N1 * (1/0) / (P)1/0 is the relative density.Fluid Density: 965.4 kg/m3.Flow Rate (Q): 360 m3/h.C = Q/N1 * (1/0) / (P)

How do you find the maximum flow of a Valve?

The volume flow rate for liquids can be calculated by multiplying the fluid velocity times the flow area. Thus, Cv is numerically equal to the number of U.S. gallons of water at 60F that will flow through the valve in one minute when the pressure differential across the valve is one pound per square inch.

What does PIU mean in HVAC?

Powered Induction Unit

What is LPS in HVAC?

KOBOLD LPS air flow switches are widely used to control air flow setpoints in HVAC duct applications. Air flow exerts a force on a paddle, actuating a dust-tight SPDT micro switch. The switching point may be adjusted continuously within a wide range, making the LPS useful in a wide variety of applications.
