A valve is a control device for a fluid line. Its basic function is to connect or cut off the circulation of the pipeline ring, change the flow direction of the medium, adjust the pressure and flow...
Driven by the “dual carbon” strategy, many industries have formed a relatively clear path for energy conservation and carbon reduction. The realization of carbon neutrality is inseparab...
In valve engineering, the Cv value (Flow Coefficient) of the control valve refers to the volume flow rate or mass flow rate of the pipe medium through the valve per unit time and under the test con...
EN 558-1 is a European standard that specifically specifies the face-to-face (FTF) and center-to-face (CTF) dimensions of metal valves in flanged piping systems, and is mainly applicable to valves ...
1. Clean the sealing surface of the butterfly valve and the dirt in the pipeline.
2. The inner port of the flange on the pipeline must be aligned and press the rubber sealing ring of the butterfly ...
Body Structure:
The valve body of flange butterfly valves is usually made by casting or forging processes to ensure that the valve body has sufficient strength and rigidity to withstand the pressur...
