GDQ47H track ball valve is suitable for petrochemical, liquefied petroleum gas storage, refinery, natural gas, compressor system, oil and gas pipeline, light industry, textile and other industries.


Product characteristics of track ball valves


1, open and closed without friction. This function completely solves the problem that traditional valves affect friction due to friction between the sealing covers.


2, the upper structure. Valves installed on pipelines can be directly checked and maintained online. It can effectively reduce device shutdown and reduce production costs.


3, single seat design. It eliminates the problem of safe use of medium in valve due to abnormal pressure rise.


4, low torque design. The valve stem with special structure can be easily opened and closed with a small hand wheel valve.


5, wedge seal structure. The valve is pressed by the mechanical force provided by the stem, and the ball wedge is pressed onto the valve seat to seal. The sealing performance of the valve is not affected by the variation of pipeline pressure difference, and the sealing performance can be reliably guaranteed under various working conditions.


6, self sealing structure of the sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline will pass evenly through the spherical cover at 360 degrees. It not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
