Our wafer-type double plate check valve (also known as butterfly check valve) is an industrial valve specially designed for efficient and reliable prevention of medium backflow. It adopts a wafer connection and a double-plate (double-butterfly plate) structure, featuring significant advantages such as short structural length, light weight, rapid opening and closing, and low water hammer pressure. It is applicable to working conditions such as water, sewage, seawater, oil products, steam and various chemical media, and is an ideal choice for pipeline systems in petroleum, chemical, power, water supply and drainage, HVAC and other industries.


The lightweight design of the double-plate valve plate results in low inertia and rapid, smooth closing action. This rapid shut-off feature can significantly reduce the water hammer pressure caused by the sudden backflow of the medium in the system, protect the entire pipeline system from impact damage, and extend the service life of the equipment.


Check Valve Of This Type Are Use One Spring Control Both Plates To Open And Close

The valve is directly clamped between the two pipe flanges by bolts, without the need for additional flanges or connectors. This design significantly shortens the structural length, making it a perfect solution for space-constrained applications.


Compared with the traditional swing check valve of the same specification, its weight is significantly reduced, lowering the requirements for the pipeline support structure and the installation cost


Simple structure, sturdy and durable: few internal moving parts, compact structure, reliable operation and low failure rate.

Easy maintenance: in most of the design, without removing the valve from the piping completely dismantled, inspection and maintenance of internal parts can be made, greatly simplifies the maintenance process.


Is a professional valve manufacturer integrating design, technical development, produce and sale service, has a solid strength and rich production experience.
