A Single Piece Ball Valve, also known as a One-Piece Body Ball Valve, is the most compact and economical design in ball valve construction. The valve body is manufactured from a single forged or cast piece, which eliminates body joints and minimizes potential leakage points. This robust structure ensures excellent strength, durability, and long-term sealing performance.
Single Piece Ball Valves are generally designed with a reduced bore (reduced port) configuration, offering efficient flow control while maintaining a compact and lightweight design. They are ideally suited for applications where frequent maintenance or internal part replacement is not required, such as water, air, oil, and general utility pipelines.
These valves are widely used in industrial, commercial, and residential systems, offering reliable shut-off in a cost-effective package. The simple construction, PTFE seats, and chrome-plated brass or stainless-steel ball provide smooth operation and excellent resistance to wear and corrosion.
