Seated valves type WV700
The BIERI series WV700 are direct operated and leakage free seated valves out of the series NG6 700 bar, suitable for highest demands. The modular principle of the major components allows a great variety of symbols – 2/2-, 3/2-, 3/3-, 4/2-, 4/3- way functions with positive or negative overlap. Hence these valves are superior and space-saving alternatives to spool valves which require additional shutoff valves.
