विशेषताहरु
1) Small in size, light in weight, compact in structure, easy in maintenance.
2) Two torsion springs are used excerting on each of the pair valve plates, which colse the plates quickly and automatically.
3) The quick-close action prevents the medium from flowing back and elimates waterhammer effect.
4) Short body structure length and good rigidity.
5) Easy installation, it can be installed on horizontal and vertical both directions pipes.
6) This valve is tightly sealed, without leakage under the pressure water test.
7) Safe and reliable in operation, high interference-resistance.
