SS 316 Pneumatic actuated Threaded three piece ball valve 150 classC-Way Engineering Exports is a trusted three piece ball valve manufacturer and exporter, supplying stainless steel, carbon steel, Duplex, Super duplex, Special Alloys and Brass 3 piece ball valves for industrial applications worldwide. Our valves are engineered for inline maintenance, zero leakage shut-off, and long service life, making them ideal for chemical, petrochemical, oil & gas, water treatment, food & beverages, pharmaceutical, and projects.
A 3-Piece Ball Valve is a high-performance industrial shut-off valve designed for reliable isolation, frequent operation, and easy inline maintenance. The valve body is constructed in three separate sections—two end caps and one central body—allowing the valve to be serviced or repaired without removing the end connections from the pipeline.
Compared to one-piece ball valve and two-piece ball valves , a 3-piece design offers superior maintainability, longer service life, and reduced plant downtime, making it the preferred choice for process industries, chemical handling, and critical service applications.
Our 3-piece ball valves are precision-machined, pressure-tested, and engineered to meet international standards for industrial, EPC, and export projects.
The valve features a robust three-piece body construction, consisting of:
This design enables quick disassembly, seat replacement, and internal inspection without disturbing pipeline alignment.
The internal geometry ensures minimal pressure drop and smooth flow control, even in high-cycle applications.
