Product Introduction
Product Description
butterfly wafer check valve is used to automatically open when media flows and then close when fluids flow backward. A check valve is also referred to as a one-way valve, a non-return valve, or a clack valve. Check valves have the ability to pass fluid in a single direction. Safety applications rely on this feature along with the capability to prevent overflow.
The opening design pressure of a check valve is the minimum pressure required upstream to open or operate. Customers can carefully match application requirements with many different types of valves.
butterfly wafer check valve Characteristics:
1. Short face to face dimension(only 1/4~1/8 of conventional flange check valve);
2. Small volume, light weight (1/4~1/20 of conventional flange check valve);
3. The disc closes rapidly,and has small water hammer pressure;
Can be used for horizontal pipe lines and vertical pipe lines.
4. Convenient utilization;
5. Free channel and small fluid resistance;
6. Excellent sealing;
7. Short stroke of valve disc and small impact force when closing valve;
8. Compact structure, beautiful modeling;
9. Long service life and reliability.

Comparison between Wafer Butterfly Check Valve and Conventional Check Valve
Structure | Wafer butterfly check valve | Conventional check valve |
Water hammer pressure | Small. Valve disc has short stroke. With assistance of spring, it can be closed rapidly. | Large. It needs long time to close for its long stroke. |
Size & Weight | Short face to face dimension, small volume, light weight | Long face to face dimension, large volume and heavy weight |
Fluid Resistance | Quite small; fluid drag coefficient: 2.6～0.7 | Quite small, fluid drag coefficient: 1.3~3. It cannot be opened |
Installing | Can be installed horizontally or vertically or vertically, without support for light weight. | Can be installed horizontally and vertically. |
Pressure | Quite low. The valve can be opened completely under low differential pressure. | High. Valve disc only can be opened completely with large differential pressure |
Reliability | Compact and simple structure | High impact fore and water hammer pressure cause damage to valve easily. |

Our butterfly wafer check valve model is a general purpose one-way flow valve. Compared with the swing valve, the butterfly wafer check valve has the characteristics of fast vertical and horizontal, air tight, stronger, lighter, smaller, and more reliable than the ordinary swing check valve.
Butterfly wafer check valve maintenance is easier due to the lighter weight and shorter face-to-face dimensions.
