Valve fitting V11-150 ball valve seat
The API ball valve seat is an evolution of the traditional plug valve, with a ball opening and closing by the ball around the stem axis for the purpose of opening and closing. The ball surface adopts advanced spraying technology, through the treatment of various working conditions, the highest hardness can reach HRC78. Valve seat sealing surface treatment, up to HRC72 hardness. Ball and seat are paired for grinding, and all sealing areas throughout the ball valve sealing surface are precision ground.
Ball valve seat is an important part of oil production pump, its use directly determines the life of oil production pump. According to the corrosion characteristics of oil well fluid, different materials can be provided. The main materials are stainless steel, cobalt chromium tungsten, tungsten carbide, titanium carbide and other alloy materials. Valve seat and ball supporting use, has excellent sealing and wear resistance, corrosion resistance, can be adapted to harsh environment. The ball valve seat incline is flat and smooth, the accuracy reaches 0-0.005mm, the surface mirrorization effect.
Product application scope:
Widely used in oil drilling, deep-sea drilling pumping pump valve ball, ball seat, which is the most critical part of the pump.
