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.
