Product Introduction
This valve is used as one-way valve in the pipeline of petroleum, chemical,food,medicine, paper making,water supply and drainage systems,metallurgy and enrgy engineering.
Product Features
1.Small in size,light in weight,compacct in construction,easy in maintenance.
2.Two torsion springs are used exerting on each of the pair plates, which close the plates quickly and automaticaly.
3.The quick-close action prevents the medium from flowing back and eliminates water hammer effect.
4.Short body structure length and good riidity. Safe and reliable in operating,high interference-resistance.
5.Easy installation,it can be on both horizontal and vertical directions pipes.
6.The valve is tightly seated, without leakage under the water pressure test.
