If you’re looking for a reliable shut-off solution that balances serviceability, pressure handling, and cost-efficiency, the Two-Piece Ball Valve is the perfect choice. At Perfect Engineers, we manufacture high-quality two-piece ball valves suitable for water, oil, steam, chemicals, and general industrial fluids across sectors.
This valve design is serviceable, robust, and easy to install, making it one of the most preferred ball valve types in the industrial world.
A Two-Piece Ball Valve consists of two separate body parts—typically joined using threads or bolts. This design allows partial internal access (mainly for ball and seat inspection), while maintaining compact construction and better sealing than one-piece valves.
These valves are widely used for medium-duty applications where occasional servicing or replacement of internal parts is required.
