What is One-Piece Ball Valve?
Valve ya kipande kimoja cha mpira ni rahisi, valve compact iliyofanywa kutoka kipande kimoja cha chuma au plastiki. Ndani, there’s a ball with a hole through it that turns to control fluid flow. These valves are popular in residential applications, such as household plumbing systems and they’re cost-effective.

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. Mwili hutupwa au kughushiwa kama kitengo kimoja, na mpira, shina, 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% bei nafuu kuliko matoleo ya vipande viwili. Tofauti hii ya bei inatokana na michakato rahisi ya utengenezaji na sehemu chache. Kofia ya chupa ina kazi ya kuweka yaliyomo kwenye bidhaa bila hewa, 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.
