Flow Coefficient (Cv) The flow coefficient or valve coefficient denoted by “Cv”, is used to determine the valve size that will best allow the valve to pass the required flow rate while providing stable control of the process fluid. Most valve manufacturers publish Cv data in product catalogues for various valve styles. Table 1 provides an Solution: From Cv Table, Cv = 365 Qa = 365 √3 or 632 gpm Problem: Find the pressure drop across a 1½" plastic lined valve 100% open with water flow of 63 gpm Solution From Cv Table, Cv = 80 ΔP = (63/80)² = 0.62 psi Flow Coefficients and Computations Sec 5: Tech Data
The top quality valve manufacturers do publish Cv values for their manual valves, and Googling as advised above will get you the information. But if you are doing a preliminary design and the valve hasn't been specified or bought yet then you will be looking for generic data and not ultimate accuracy.

Severe damage may occur to other valve styles. When using globe valves for throttling, do not operate the valve continuously at less than 10% open. • All valves shall only be used within their defined boundary conditions. All standard materials of construction, including
Hi guys. Any of you ever see a table of Cv's for manual globe valves vs. travel? I can find the Cv for the valve at 100% open easily enough, but have not thus far found anything for any manual globe valve for Cv … Globe valve 1.5 ％ 30：1 Item Pressure loss（ξ） Flow characteristics Rangeability Item Ball valve 0.05 Quick open 3：1 Data-01 P＝Constant Cv ％ Linear Valve opening ％ 1 0.2 2 1.5 5 0.2 0.7 020 40 6080100 0 20 40 60 80 100 Pressure loss Butterfly valve 0.3 Equal ％ Gate valve 0.2 Quick open Comparison of Cv value （Butterfly valve=1）
