Features:
1. Small in size, light in weight, compact in structure,easy in maintenance.
2. Two torsion springs are used excreting 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. Short body structure length and good rigidity.
5. This valve is tightly sealed, without leakage under the pressure water test.
6. Safe and reliable in operation,high interference-resistance.
