Introduction
High-precision tungsten-cobalt cemented carbide balls are widely used in oil
drilling and deep-sea drilling oil pump valve balls and ball seats, which are
also one of the most critical components in oil pumps. Due to the harsh working
environment and conditions in the oil drilling industry, sand-containing wells,
heavy oil wells, and high-pressure anti-oil wells usually contain water,
various gases, wax, sand and other highly corrosive substances. The oil pump
needs to extract oil from hundreds or even thousands of meters of formations,
which requires its valve ball and valve seat to have good sealing, wear
resistance and corrosion resistance (the valve ball and valve seat are vacuumed
to an absolute pressure of less than 0.36kgN/cm after matching, and the
absolute pressure value does not change within 10s).

Advantages
1. It has the lowest theoretical flow resistance (flow resistance refers to the
ratio of the pressure difference on both sides of the sound-absorbing material
sample to the linear velocity of the airflow passing through the sample under
stable airflow conditions.);

2. Excellent chemical stability and wear and corrosion resistance, can be in
contact with most liquids and some corrosive media;

3. Under high temperature and high pressure environment, it can still achieve
complete sealing (nominal pressure from vacuum to 42MPa);

4. Since the carbide ball valve uses the ball as the opening and closing part,
it is less affected by friction and can achieve fast opening and closing (can
be controlled within 0.05-0.1s), and the operation has less impact. In
addition, the spherical closing part can withstand a higher pressure difference
when closing, and can also achieve automatic positioning;

5. It has bidirectional sealing, making the work more stable and reliable.

Applicable
1. Carbide ball valves are suitable for use in two-position adjustment,
pipeline systems with high requirements for sealing performance, rapid opening
and closing (1/4 turn opening and closing), large pressure difference, small
operating torque, small flow resistance, and cavitation or vaporization
phenomena;

2. Pipes with certain corrosive media;

3. In low-temperature deep-freezing devices or high-temperature and high-
pressure pipeline systems;

4. Full-bore welded carbide ball valves can be used in oil pipelines and gas
pipelines that need to be buried underground;

5.Specially designed V-shaped opening structure carbide ball valves can also
have certain adjustment functions.
