Flange Reduced Steel Welded Ball Valve

Valve Body: Usually made of materials such as carbon steel, stainless steel or alloy steel, it has good corrosion resistance and mechanical strength, capable of withstanding the pressure in the piping system and the erosion of the medium.

Ball: As a crucial part of the valve, it is generally made of the same or a higher-grade material as the valve body to ensure good wear resistance and corrosion resistance. The surface of the ball is precisely machined to form a good sealing fit with the valve seat.

Valve Stem: Used to control the rotation of the ball, thus realizing the opening and closing operations of the valve. The valve stem needs to have sufficient strength and rigidity to ensure the stable transmission of torque during the operation process.

Valve Seat: Responsible for ensuring the sealing performance of the valve and preventing fluid leakage. The valve seat usually adopts a metal valve seat with a polymer sealing ring, such as PTFE (Polytetrafluoroethylene), RPTFE (Reinforced Polytetrafluoroethylene), Viton (Fluorine Rubber), Nylon (Nylon), PEEK (Polyetheretherketone) and other materials.

Sealing Ring: It further enhances the sealing performance of the valve and prevents the medium from leaking through the gap between the valve body and the valve stem.
