The graph shows how Varibell® in the size 1/2", 1", 11/2", 2", 3", 4" and 6" can cover all flow ranges for which conventional valves would require size ranges 1/2" to 10" diameter.
This is possible due to the extremely high turndown ratio of 1:10.000.
KVS Values
| Varibell® DN | 150 | KVS = 1700 |
| Varibell® DN | 100 | KVS = 700 |
| Varibell® DN | 80 | KVS = 445 |
| Varibell® DN | 50 | KVS = 185 |
| Varibell® DN | 40 | KVS = 140 |
| Varibell® DN | 25 | KVS = 33 |
| Varibell® DN | 15 | KVS = 13 |
| Varibell® DN | 15VE | KVS = 5 |
Varibell® is a rotary quarter turn valve. The regulating element is a bell shaped plug, featuring tear drop shaped apertures machined into both inlet and outlet but laterally reversed. During opening, this plug rotates and simultaneously uncovers the two tear drop apertures giving fine flow adjustment with a 2 stage pressure reduction across both seats.
