Wide ball valve has its own structure is unique to some of the advantages, such as switch without friction, seal is not easy to wear, open and close torque. This reduces the size of the actuator. Equipped with multi turn electric actuator, can realize the adjustment of the medium and tight cut off. Widely applied to water, steam, oil, chemical industry, urban water supply and drainage, such as strict cut-off conditions.
The closure of the ball valve is a ball, the ball around the center line of the body to achieve the opening and closing of a valve. Ball valve in the pipeline is mainly used to do the cutting, distribution and change the direction of the flow of media. Wide ball valve is widely used in recent years, a new type of valve, the general level of the installation of the valve.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.

Structure characteristics:
1, open and close without friction. This feature completely solved the traditional [/wiki] valve [wiki] due to the friction between the sealing surface and the impact of the problem of sealing.
2, jacket type structure. The valve installed on the pipeline can be directly online inspection and maintenance, can effectively reduce the device to stop the car, reduce costs.
3, single seat design. Eliminates the valve in the cavity due to abnormal pressure and affect the use of security issues.
4, low torque design. Special structural design of the stem, just with a small handle valve can easily open and close.
5, wedge sealing structure. Valve is to rely on the mechanical force of the valve stem, the ball wedge pressure to the valve seat and seal, so that the valve seal is not affected by the pipeline pressure difference, in various conditions, the sealing performance has a reliable guarantee.
