Electric stainless steel floating ball valve-Electric valve series-电动阀厂家-上海冠环阀门制造有限公司

Product overview

Electric stainless steel floating ball valve is composed of intelligent electric actuator and stainless steel ball valve assembly, using a soft seal structure. Ball valve flow channel is straight through, small flow resistance, strong flow capacity, less medium retention. The ball center of the ball valve is stainless steel, which is smooth by fine grinding. When the ball is switched, it can rotate with the sealing surface without clearance to ensure the sealing of the valve. By accepting (4-20mA) industrial signals driven by (220V, 380V) power supply voltage, the valve stem is driven by the rotation of the ball center to achieve switching and adjustment. Mainly used in natural gas, water, solvent, weak acid, slightly rotten gas, liquid and other transmission pipelines as a medium flow switch and regulation.

Product characteristics
1, the fluid resistance is small, ball valve is a small fluid resistance in all valve classes, even if it is a ball valve, its fluid resistance is quite small.
2, the thrust bearing reduces the friction torque of the valve stem, and can be balanced and flexible for long-term operation using the valve stem.
3, the sealing performance of the seat is good, the sealing ring made of polytetrafluoroethylene and other materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of the pressure of the medium.
4, the valve stem seal is reliable, because the valve stem only for rotating movement without lifting movement, the filling seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.
5, because the polytetrafluoroethylene material has good self-lubrication, the friction loss with the ball is small, and the service life of the ball valve is long.
6, the lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
