V11-125 Blank Tungsten Carbide valve seats for API Oil Valves
Features of tungsten carbide valve seats
1. Valve balls and valve seats are widely used in oil fields.
2. Valve Ball and Seat performance directly affects the use effect and service life of the sucker rod pumps.
3. Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
Tips of tungsten carbide valve seats
-The detachable surface parts in valve are used to support the valve spool in the fully closed position and constitute a sealed part. Generally, valve seat diameter is the maximum flow diameter of the valve.
-Elastic sealing material and small actuator's thrust force is used to obtain tight seal of air bubble, compression valve seat's sealing stress elastically deforms the material and squeezes it into the rough surface of the matching metal part to block all leakage paths.
-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.
