Flow Data
Cv are measured at the valve. Therefore restrictions in end connections may reduce flow.
Factory Test
Every valve is tested with the nitrogen @68 bar (1000 psig) for leakage at the seat to a maximum allowance leak rate of 0.1 scc/min. The stem packing is tested for no detectable leakage. |
