It is a pretty important kind of pipeline pressure component for industrial automation process control, usually used for remote opening and closing control. Electric actuated ball valve adopts an integrated structure, it can be controlled by single-phase power supply AC220V and DC power supply 24VDC. The competitive features of electric actuated ball valve are that small size, reliable performance, simple matching and the large circulation capacity. Due to the powerful function of the electric actuated ball valve, it has been widely used in nuclear power, drainage, heating and other industries.
