Metal sealed orbital ball valves are suitable for petrochemical, LPG storage, refineries, natural gas, compressor systems, oil and gas transportation pipelines, light industry, textile and other industries.

Product features

1, opening and closing without friction. This feature completely solves the problem of traditional valves affecting sealing due to friction between sealing surfaces.

2、Top-mounted structure. The valve installed on the pipeline can be directly online inspection and maintenance. Can effectively reduce the device stop, reduce production costs

3、Single valve seat design. Eliminate the valve cavity media due to abnormal pressurization and affect the use of safety issues

4、Low torque design. Special structural design of the valve stem, just with a small handwheel valve can be easily opened and closed

5、Wedge seal structure. The valve is relying on the mechanical force provided by the valve stem, the ball wedge pressure to the valve seat and sealing. So that the sealing performance of the valve is not affected by changes in pipeline differential pressure, in a variety of operating conditions, the sealing performance are reliably guaranteed!

6, the sealing surface of the self-cleaning structure. When the ball is tilted away from the valve seat, the fluid in the pipeline will pass uniformly along the sealing surface of the ball into 360 °. Not only eliminate the high-speed fluid on the seat of the local scouring, but also flushed away the sealing surface of the accumulation of material, to achieve the purpose of self-cleaning!
