Electric butterfly valve model preparation method, electric butterfly valve code naming method, only suitable in China.
With the increase in demand for valves in my country’s industrial manufacturing industry, electric butterfly valves have become a more prominent one among many valves. However, due to the wide variety of electric butterfly valves, and the difference in control modes and medium pressure and temperature, users often choose electric Uncertainty about butterfly valve models! In order to avoid such a situation, our company specially provides the electric butterfly valve model preparation instructions for your reference and understanding!
The electric butterfly valve model preparation instructions include the addition of additional conditions for the butterfly valve, the difference in connection methods, the upgrade of the transmission mode, the change of the structure, the level of valve pressure, and the requirements for temperature, pressure, corrosion and material. Hope It is helpful to everyone in the selection!
