Butterfly Check Valve - China
price: 100.00 Dollar US$
The butterfly check valve is able to prevent medium from backflow.
It is often used to stop medium backflow in pipeline for industries such as petroleum, chemical, hydraulic power generation.
Features
1 - The check valve can prevent medium from backflow.
2 - Automatic Operation Mode : when the medium flows forward, the valve disc will be opened under the fluid pressure, when it flows backward, the disc will be closed under the action of fluid pressure and disc’s weight
3 - The rubber valve seat makes for the reliable sealing performance of the check valve.
4 - Produced with double springs, load is dispersed equally to the valve disc.
So the butterfly check valve can be closed immediately when the medium flows back.
