High Precision Tungsten Carbide Valve Seat with Mirror Polishing

Tungsten carbide valve seat, belongs to oil tool component for oil and gas industry.
We also call it oil valve head, which is specialized in oil sealing usage. This kind of parts become increasingly well received due to its high hardness, high density, high strength and stable chemical performance.
And its good flexural strength, impact toughness, makes the cemented carbide seat in improving the use of oil drilling pump performance beyond other material selection, excellent wear resistance and corrosion resistance improves the drilling efficiency, prolong the service life of the tool, also reduces the working activity cost.

The working environment and condition of oil and gas drilling industry is very severe, usually in deep manholes, heavy oil, high pressure oil resistance contains water, gas, wax, sand and some high corrosive substances, pumping oil from hundreds or even thousands of meters underground strata, this requires the valve seat to have good sealing, wear and corrosion resistance.

The cemented carbide high precision tungsten carbide valve seat, is made according to the requirements of machinery sealing purpose as per the drawings customized, the measurements are:
1. φ110*φ90-φ50-20°*4-φ15-φ9*25,
2. φ79*φ75*SRφ76.2*φ56*φ44.5*20.

Tungsten carbide valve seat, usually is used together with tungsten steel valve ball, carbide valve auxiliary, valve sleeve. Key precision machining is the accurate angle to ensure the sealing requirements of the closure of the valve ball assembly, inner hole and taper radian mirror polishing, emitting a shiny metallic luster.

The application is constantly increasing, and towards high temperature, high pressure, high sealing, larger diameter, easier to adjust, longer service life and multifunctional development direction. Its reliability and comprehensive performance have reached a high level, will replace part of the gate valve seat, regulating seat and stop seat. The innovation of carbide valve seat technology means a lot to us in oil and gas pipelines and oil refining cracking units.
