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.
