The electric three-piece flange ball valve is a type of ball valve that uses an electric actuator to control the opening and closing of the valve. It consists of three distinct sections: two halves of the ball, and the third section is a sealing seat ring. The electric actuator controls the rotation of the ball by driving the motor, thereby achieving the opening and closing of the valve.

Structural Features
- Three-Piece Structure: The three-piece ball valve consists of three main components: the valve body, ball, and valve seat. This design ensures convenient installation and maintenance. The ball and valve seat are connected flexibly, allowing for easy disassembly and replacement.
- Flanged Connection: The flanged connection offers advantages such as easy installation, excellent sealing performance, and wide applicability, meeting connection requirements under various operating conditions.
- Metal Sealing: The three-piece ball valve uses metal seals, which provide good wear resistance, pressure resistance, and high-temperature performance, significantly enhancing the valve's sealing capability and service life.
- Seat Seal Ring: The seat seal ring, typically an O-ring or V-ring, offers excellent elasticity and self-sealing properties. It automatically compensates for wear between the seat and ball, ensuring long-term sealing performance.
- Bi-Directional Sealing: The three-piece ball valve features a bi-directional sealing design, preventing both medium leakage and external contamination, thereby ensuring safe system operation.
