API V11 Tungsten Carbide Valve Seats Ball HRA 89 Grinding Smooth Surface
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.
