Two Piece ball valve

Two-Piece Ball Valve – Stainless Steel, Threaded & Flanged - C-Way Engineering Exports

At C-Way Engineering Exports, we manufacture premium-quality Two-Piece Ball Valves engineered for high reliability, corrosion resistance, and long service life in industrial piping systems. Designed in compliance with ASME B16.34, API 608, ISO 17292, DIN 3357, and EN 1092-1, our valves deliver exceptional shut-off performance and durability in chemical plants, oil & gas facilities, water treatment systems, and global process industries.

Overview of Two-Piece Ball Valves

Our Two-Piece Stainless Steel Ball Valves are precision-built using SS304, SS316, carbon steel, duplex, Alloy steel, Brass, Bronze and lead-free brass. Available in threaded, socket weld, butt weld, and flanged end connections, these valves provide bubble-tight sealing, low torque operation, and easy maintenance—ideal for high-pressure and high-temperature pipelines.
