Advantages of double disc check valve

A. Short structure, small volume and light weight bring great convenience for valve installation, handling, storage and pipeline layout,

And can save costs.

B. The line vibration is reduced. In order to reduce the line vibration to a small limit or eliminate the line vibration, close the check valve as soon as possible before the liquid flow has a chance to reverse flow.

The size of each disc in the double disc check valve is only the size of the full structure check valve disc in the early morning, which reduces the fluid resistance and can

Quickly move to the closed position. Their radius of rotation is only half that of conventional check valves. Its leading edge distance from the open position to the closed position is halved,

This reduces travel time to 50%

C. To reduce water hammer, compared with all full structure swing check valves, the weight of the flap of the double flap check valve has been greatly reduced, which can reduce the slamming and

The water hammer phenomenon is reduced to a small extent.
