The sequence codes of general butterfly valve models are: butterfly valve model code, butterfly valve transmission mode, butterfly valve connection form, butterfly valve structure form, butterfly valve sealing surface material or lining material, butterfly valve nominal pressure and butterfly valve body material, which is the most basic arrangement mode at present.
The above is a brief introduction to the specifications and models of butterfly valves. From the above, we can know that butterfly valves are widely used, not only in general industries such as petroleum, natural gas, chemical industry and water treatment, but also in the cooling water system of thermal power plants. When installing the butterfly valve, we should pay attention to the following problems: the disc should stop at the closed position, the open position should be determined according to the rotation angle of the butterfly plate, and the butterfly valve with bypass valve should be opened before opening. I hope the introduction of these butterfly valve specifications can help you, and you can continue to pay attention to our Tuba Rabbit website.
