YN8 non-magnetic V11-375 polished Tungsten Carbide saddles for sealing valves of oil pumps
Features of tungsten carbide saddles
1. Valve balls and valve saddles are widely used in oil fields.
2. Valve Ball and saddles performance directly affects the use effect and service life of the sucker rod pumps.
3. Each ball-and-saddle combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
Tips of tungsten carbide saddles
-We can supply tungsten carbide ball and valve seat with high precision.
-With high corrosion and wear resistance, and high strength and temperature resistant, our valve balls (tungsten carbide pellets) and seats are exported to many countries.
-Made of tungsten carbide, Tungsten Carbide round Balls/cemented carbide ball/hard alloy ball is also called hard alloy balls. It is used for places requiring extreme hardness and resistance to wear and abrasive, hard shocks and impacts.
-Tungsten carbide saddles can be used for special valves, flow meters, recirculating balls bearing screws, liner bearing and balls for ball point pens. They are also used for mining, as pivots and points of compotation. What's more, they are also used for measurements or calibrations of holes and measurement checking devices.
