Comparison with Two-Piece Ball Valves

One-Piece vs. Two-Piece Ball Valves:

Structure Differences
One-piece ball valves have a single solid body that contains all components. The body is cast or forged as one unit, with the ball, stem, and seats assembled through the end. Two-piece ball valves, on the other hand, split into two parts.

Cost Comparison
One-piece valves are generally 30-40% cheaper than two-piece versions. This price difference comes from simpler manufacturing processes and fewer parts. ទោះយ៉ាងណាក៏ដោយ, when considering long-term costs, two-piece valves might save money since they can be repaired rather than replaced.

Installation and Handling
One-piece valves are lighter and more compact, making them easier to install in tight spaces. Since there are fewer joints, they’re also less likely to leak. Two-piece valves are slightly bulkier.
