3 Piece Ball Valve
Description3 Piece Ball Valve Manufacturer
3 Piece Ball Valve is a widely employed valve type in industrial pipelines where maintenance simplicity, excellent sealing capabilities, and durability are the main priorities. In contrast to standard valve designs, three-piece construction enables removal of the middle body without disconnecting the valve from the pipeline.
Being the most trusted 3 Piece Ball Valve Manufacturer and supplier in India, we offer high-quality valves which will be effective in any industrial application. Among our valve types you can find SS 3 Piece Ball Valve, Stainless Steel 3 Piece Ball Valve, SS304 3 Piece Ball Valve, Floating Ball Valve, Manual Ball Valve, Pneumatic Ball Valve, and Electric Ball Valve.

What is a 3 Piece Ball Valve?
Three Piece Ball Valve is an isolation quarter-turn valve that features three separate body parts connected with bolts. The middle part contains the ball, seats, and stem, while the other two ends stay permanently connected to the pipeline when performing the maintenance.
The three-piece structure makes servicing very easy since the inside parts can be viewed, cleaned or replaced without taking out the entire valve from the pipeline. This helps to cut maintenance costs and avoid production downtime.
Features of Asten 3 Piece Ball Valve

End Connection Options
Threaded End
The 3 Piece Ball Valve with threaded ends is most appropriate for small piping systems that need quick assembly and easy replacement.
Flanged End
The 3 Piece Ball Valves with flanged ends are suitable for industrial pipelines that have medium and high pressures.
Socket Weld Ends
Socket weld connection provides leak proof joints for small pipe sizes.
Butt Weld Ends
Butt weld end valves are useful for high pressure and high temperature applications.
3 Piece Ball Valve – Working Principle
The principle behind the operation of the 3 Piece Ball Valve lies in its quarter-turn functionality. The rotation of handle/actuator through 90 degrees results in the rotation of the ball inside the valve.
When the ball and the bore of the valve are aligned, fluid flows through with little obstruction. Turning the ball at right angles to the flow direction closes off the flow passage and allows positive shut-off.
Applications of 3 Piece Ball Valve
This Stainless Steel 3-piece ball valve is extensively employed in many industries because of its ruggedness, non-corrosiveness, and maintenance-free design.
- Chemical processing – Effective handling of corrosive process media in industrial settings.
- Pharmaceutical – Hygienic flow control in pharmaceutical production plants.
- Food & Beverages – Applicable in sanitary applications needing clean and uncontaminated flow.
- Water treatment – Control of water distribution and water treatment process.
- Oil & Gas – Efficient operation in upstream, midstream, and downstream pipeline systems.
- Petrochemical – Industrial applications involving difficult chemical processes with different pressures.
