Cv manual globe valve

 · For the required accuracy of the process control, one can't just depend on turning hand wheel of the manual global valve to have the proper Cv. Instead, it may need to be used with the certain process instrumentation, such level, flow, or pressure indicators while operating these manual global valves. cv value stop valve (globe valve) 18 22 29 57 78 full-open cv value mm 15 20 25 30（32） 40 50 65 80 inch 1/2 3/4 1 1 1/4 1 1/2 2 2 1/2 3 4 full open cv value sediment strainer (type y) 14 26 34 50 93 0 50 cv value (%).

Velan is a world leader in the design and production of a wide range of cast and forged steel gate, globe, check, ball, triple offset, highly engineered severe service valves, and steam traps offering superior performance across all major industrial applications. cv value stop valve (globe valve) 18 22 29 57 78 full-open cv value mm 15 20 25 30（32） 40 50 65 80 inch 1/2 3/4 1 1 1/4 1 1/2 2 2 1/2 3 4 full open cv value sediment strainer (type y) 14 26 34 50 93 0 50 cv value (%) opening degree (%) 0 10 20 30 40 50 60 70 80 90 stop valve (globe valve): 15 mm. The Flow Coefficiency (Cv) of a valve is the rate of gallons per minute of water at 60° F through a fully opened valve at a pressure drop of 1 PSI across the valve. Size 2 42 42 42 45 38

24 มิ.ย. Cv is a relative value which measures flow rate for a given pressure delta across the valve. The bigger the Cv, the more flow a valve can pass.
