Highlight: 3-Piece Electric Ball Valve
Product introduction:
The valve body of a 3-piece ball valve is composed of one main valve body and two auxiliary valve bodies, hence the name
"3-piece ball valve". After the ball core and valve stem are installed in the main valve body, the auxiliary valve bodies are
fitted with valve seats, and the main and auxiliary valve bodies are connected into one piece by bolts. Its ball core flow
channel also has a full bore size. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction
of media. The 3-piece ball valve is a new type of valve that is widely adopted. The main feature of a 3-piece ball valve is its
convenient online maintenance. By loosening the screws on the valve body and removing a bolt passing through the main
valve body, the main valve body can be rotated to replace the valve seat seal ring. Additionally, the main valve body bolts
can be completely removed to take out the main valve body for maintenance, while the auxiliary valve bodies remain on the
pipeline. This avoids dismantling the entire ball valve and greatly reduces maintenance workload.

Product features:
1. High Reliability: The 3-piece ball valve features a compact structure, excellent sealing performance, flexible operation,
and convenient maintenance, making it highly reliable.
2. Low Flow Resistance: With a large sealing surface between the ball and the valve seat and an unobstructed flow path, it
exhibits low flow resistance and superior flow characteristics.
3. Long Service Life: The minimal friction between the ball and the valve seat ensures a long service life.
4. Full Open/Full Close Functionality: The 3-piece ball valve can achieve full open and full close operations, facilitating
precise control of medium flow.
5. Wide Applicability: It is suitable for special working conditions such as high temperature, high pressure, and corrosion
resistance, demonstrating excellent adaptability.
