Having learned a lot about butterfly valves, but still faced with a wide range of butterfly valves, we have no choice, which only means that we have not really understood the advantages and disadvantages of each valve. Take the electric butterfly valve for example, what are its advantages? What kind of occasion is it suitable for? Do you understand?

Therefore, appropriate materials should be selected to prolong the service life of gate valves. For others, it is necessary to consider the impact of high temperature time limit on material process performance, such as changes in flexibility and stress corrosion. When the temperature reaches the standard or exceeds the quenching temperature, the valve internals will cause quenching, tensile strength reduction and other problems. In order to avoid the change of material tensile strength, the maximum temperature limit must be selected within a safe range.
