Titanium ball valve
【 features 】
The traditional ball valve, floating or fixed sphere and valve seat contact all the time, switching torque, the sealing surface is easy to damage, orbit ball valve opening and closing, the sphere deflection first, and then turn to switch sphere and valve seat during the whole process from, so the seat will not be scraped, and open-close torque is small.
1, the opening and closing without friction. This function completely solve the traditional valve for sealing surface friction each other and affect the sealing problem.
2, the structure of the jacket type. The valve can be directly mounted on the pipeline on-line inspection and maintenance. Can effectively reduce the parking device, reduce the production cost.
3, single seat design. To eliminate the influence due to abnormal pressure valve lumen medium use safety problems
4, low torque design. Special structure design of the valve stem, only with a small hand wheel can be easily opening and closing of the valve
5, wedge seal structure. Valve by valve stem provides mechanical force, wedge pressure the ball into the seat and seal. The valve sealing performance is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee
6, wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Ball rotated 90 degrees in the inlet and outlet should be completely present spherical, thereby blocking flow.
7, the structure of the sealing surface of self-cleaning. When the ball tilting away from the seat, fluid in the pipeline along the sphere uniform sealing surface into 360 ° through, not only eliminates the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.
【 product use 】
GDQ47H PN16 ~ PN100 orbit type titanium ball valve is suitable for the petrochemical industry, liquefied petroleum gas storage, natural gas, oil refineries, compressor, oil and gas pipeline system, light industry, textile and other industries.
