Mechanical Sealing rings
1. Good materials, advanced process, stable Mechanical
properties,
2. high wear resistance and corrosion resistance.
3. Various sealing rings with complicated shape, either blanks or finished products can be provided.
As an ISO 9001:2000 company, CPM has the tools, people and confidence to meet or exceed the most rigorous specifications required by our customers. Our products are currently enjoying growing market share globally and we are committed to firmly establishing CPM as the standard of quality worldwide.



Valve Ball and seat
Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and as pivots, detents and tips for gauges and tracers. Tungsten carbide itself is practically inert and extremely strong. Any attack is usually on the binder. Since other material is less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more resistant binder can be supplied.
Additional ball specification
ball roundness : 0.0001 inch (0.003 mm) maximum; ball surface roughness : 5RA maximum;
tolerance shall to be ��0.001 inch (��0.025mm) for all ball diameter less than 2-inchs;
tolerance shall to be ��0.002 inch (��0.050mm) for all ball diameter not less than 2-inchs(precision grade : excess or equal to 25).
