301K 系列是一種直通球閥，其球體只需繞軸 1/4 圈，就能實(shí)現(xiàn)全開至全閉或全閉至全開動作。
該球閥具有極優(yōu)的切斷性能，當(dāng)全開時，其流路和管路內(nèi)徑基本相同，流體壓力損失極小，因此于各種液體、氣體、料漿類等液體的切斷控制。
This 301K series provides ball vavles with a special inner valve which can be fully opened or closed by simply causing the stem to make a 1/4 turn.
The offtake from a ball valve, when totally opened, has the same bore as the pipeline and its fliud resistance is negligible. For this reason, this automatic valve is best suited to on-off service, controlling various types of liquid, gas and slurry.
