V11 tungsten carbide Valve ball and seat
Technic parameters
The valve ball and seat will be produced and checked according to API Specification 11 AX:2006 and GB/T18607-2008(Chinanationalstandard)Their dimension reachs a accuracy of class IT6~IT7, the shape and position reach aaccuracyofclassIT5~IT6,their roughness reachs Ra 0.8~Ra 0.05μ m, and the roundness of valve ball reachs 0.002 μ m, respectively.
Technic level
The material of products has excellent properties, such as good wear and corrosion resistance, good ability ofanti-compression and thermalshock.The products have not only a higher accuracy and also a good sealing character(5seconds without leakage under a vacuum of 85 Mpa), and their production technology reachs an advanced level in China.

1. Material: tungsten carbide ( cobalt-base alloy, nickel -base alloy )
2.Application fields: Subsurface pump/Oilfield Tubing pump/Insert pump, sealing, it is widely used in petroleum industry and other anti-corrosion machine parts.
3. Properties: Seat-ball valves for oilfield Insert Pumps have good resistance against corrosion and oxidation;
Tungsten carbide valve ball and seat are widely used in petroleum drill and exploitation equipment. It's used to the stationary
and roving unidirectional valve in various tube-type oil suction pump due to their high hardness, wear and corrosion resistance as well as good anti-compression and thermal shock characters with a high pump effect.
