PBQ640F- 16 C forged steel sealing flange half of an eccentric valve.

1. The fluid resistance is small, its resistance coefficient with section of equal length.

2. Simple structure, small volume, light weight.

3. Cutting function, in the closed to the media clutter (branches, textile bags, etc.) cut off

4. Closely reliable ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system.

5. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

6. Easy maintenance, ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.

7. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.

8. The applicable scope is wide, 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.

Products are divided into: according to the use of general valve, the pipeline valve, slurry valve, gas valve, oil, chemical valve, pulverized coal injection special valve six big series. Transmission means has manual, pneumatic, electric three, eight classes (pn0.25 ~ 10.0 mpa) hundreds of specifications (40 ~ 1000) and a half ball valve products. In petroleum, chemical industry, metallurgy, electricity, gas, etc is gate valve, globe valve, y type valve, ball valve of updated products. Is now popular in the steel industry of pulverized coal injection, pulp, mother liquor and alumina powder conveying alumina industry, electric power industries hydraulic ash (or dry), petrochemical industry, gas industry, etc.
