Featutes
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 close the plates quickly and automatically.
3.The quick-close action prevents the medium from flowing back and eliminates water-hammer effect.
4.This valve is short in length,so that it is rigid and easy to mount.
5.It is easy to install on pipeline which is laid horizontally or vertically.
6.This valve is tightly sealed without leakage under the pressure water test.
7.Safe and reliable in operation,high interference-resistance.
8.The connection dimensions of flanges accord with the standards of GB4216-84 GB4216.84
9.The face to face dimensions are in accordance with GB12221-89.ISO5752-82.The stem of the valve should be perpendicular to the horizontal level when the valve is mounted on horizontal pipeling.For vertical installation the direction of flow should be downward.
