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

Product overview

The electric eccentric half ball valve is composed of the eccentric half ball valve and the electric actuator. The product has the advantages of small opening force, stable performance, good sealing and compact structure. The eccentric half ball valve uses the eccentric valve body, eccentric ball and seat, and the stem is automatically centered in the common track when rotating, and the closing process is tighter and tighter to fully achieve the purpose of good sealing. The ball and seat of the valve are completely separated, eliminating the wear of the seal ring and overcoming the problem that the traditional ball seat and the ball sealing surface are always worn. Suitable for sewage, paper making, petrochemical, natural gas medium and particle containing fluid, powder solid, especially for steel, aluminum, paper making, petroleum, metallurgy and other industries.

Product advantage
1, to solve the metallurgy, paper industry particles, powder, pulp and other media in the operation of precipitation, easy to scale, resulting in poor valve seal problems.
2, the switch is light, the ball is separated from the shell when it is opened, without any contact, the starting torque is small, and the rotation is flexible. When closed, the squeezing and cutting action between the hemisphere and the seat can remove the dirt on the sealing surface, so that the valve can be opened and closed smoothly, with high safety factor and good sealing performance.
3, the eccentric structure of the sealing surface, so that the sphere can automatically compensate for wear, can ensure the sealing performance of the valve, and will not leak, the use of this valve control pipeline safety performance is high.
4, the valve electric drive, very convenient, you can also choose the right torque according to the customer's working conditions, the brand of electric grip. Remote control can also be selected according to the working condition
