Advanced Composite Valves
4855 Broadmoor AveExperience has shown that control valve applications frequently require valves to be sized smaller than the adjacent piping to obtain satisfactory control. In many cases, especially with small NPS valves, reduced flow area and characterized trims are required.
Recognizing this, Nil-Cor has established a series of standard port sizes that cover most applications:
Ball Valve Capacity Cv | |||||||
---|---|---|---|---|---|---|---|
V-Port Trim Sizes | |||||||
Valve Size | Full Area Cv | Linear Cv | 15-deg. | 30-deg. | 60-deg | 90-deg | |
1" | 75 | 1, 3, 9 | 8 | 19 | 34 | 50 | |
1-1/2" | 115 | 3, 8, 16 | 10 | 25 | 47 | 80 | |
2" | 135 | 4, 8, 15, 20 | 13 | 27 | 53 | 110 | |
3" | 350 | 22, 37, 65 | 35 | 60 | 119 | 275 | |
4" | 540 | NA | 70 | 108 | 211 | 375 | |
6" | 1240 | NA | 175 | 248 | 484 | 800 | |
