Advantages of electric control valve: In addition to the features of high reliability, full function and ultralight, electric control valve also has the following advantages:
⑴ The power supply is convenient and economical, which saves a series of costs for the establishment of the gas source station; ⑵ The complicated way of "pneumatic valve+electric valve positioner+air source" not only increases the cost, but also brings about a decline in reliability (the more links, the more factors of poor reliability); ⑶ From the economic point of view, in addition to the cost of the gas source station, it also saves the cost of the electric valve positioner: a good imported electric valve positioner is usually more than 5000~6000 yuan, preferably at the price of 8000~10000, which can basically buy back the above highly reliable electronic actuator; ⑷ The links are reduced, and the maintenance workload is correspondingly reduced.

The electric ball valve, like the electric butterfly valve, is a new type of valve designed through further improvement and innovation on the basis of the original valve. The operation mode between them may be slightly different. The starting form of the electric ball valve is that a ball rotates through the drive of the valve stem, and the opening work is completed through such movement. Generally speaking, this kind of electric ball valve is often used in cutting off and connecting pipelines. It also has very effective control for fluid regulation and control.
