Wafer check valve is also known as reverse flow valve, check valve, back pressure valve and one-way valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. The valve used to prevent the backflow of the medium belongs to an automatic valve. Its main function is to only allow the medium to flow in one direction and prevent the flow in the opposite direction. , Prevent the reverse rotation of the pump and the drive motor, and the discharge of the container medium. Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves are used in piping systems
EN1092 BS4504 DIN carbon steel wire buckle flange is a special kind of flange in all pipelines. It uses the screw thread as a way to combine the internal thread of the flange with other fittings with external threads in the pipe or pipeline. The advantage is that it does not leak, the pressure is strong, and it is easy to load and unload. The disadvantage is that it is only suitable for pipelines within DN200. It is a special kind of flange in general industrial drainage, civil...

The disc of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum opening. Compared with the gate valve, the wafer butterfly valve has the characteristics of simple structure, small volume and light weight. It consists...
Flanged soft sealing butterfly valve has novel design structure, small overall size and light weight; the disc adopts double eccentricity, which opens and closes quickly, and the operation is light and labor-saving; there is no sliding friction between the disc and the sealing ring, and the sealing surface is wear-resistant and has a long service life. , The sealing is reliable and easy to adjust. Vertical plate structure, the valve stem is an integral metal hard sealing valve, the sealing ring...
Stainless steel ball valve and plug valve are the same type of valve. Its closing member is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing. Stainless steel ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It is a new type of valve that is widely used. The stainless steel ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal...
