Ball Valve Components for Industriel

The cemented carbide valve ball and seat will be used widely to the stationary and roving unidirectional valve in various tube-type and rod-type oil suction pump due to their high hardness, wear and corrosion resistance as well as good anti-compression and thermal shock characters with high pumping effect and a long pump check cycle for raising of sand, gas and wax containing thick oil from titled wells.A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.The material of products has excellent properties, such as good wear and corrosion resistance, good ability of anti-compression and thermal shock. The products have not only a higher accuracy and also a good sealing character (5 seconds without leakage under…
