注意：安裝在水平管道中時閥桿應和水平面垂直，豎直安裝時水流應向下
Dual plate wafer check valve
Product introduction
The wafer type butterfly check valve, a energy-saving product, is manufactured based on relative international standards, This product is featured by excellent retaining performance, high safety and reliability low flow resistance and effective to prevent from backflow of medium.it is suitable for systems in the industrise of petrochemical,food processing,medicine,textile,papermaking,water supply and sewage,metallurgy,energy and light industry etc used as a single valve.
Features:
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 watter-hammer effect.
4.safe and reliable in operation,high interference-resisitance
5.it is easy to install on pipeline which is laid horizontaly or verticaly.
Note: the stem of the valve should be perpendicular to the horizontal level when the valve is mounted on horizontal pipeline,for vertical installation the direction of flow should be downward.
