■ introduction

The straight through type Qiong valve is a kind of ball, which can realize the action of full open, full close or full close full open only when it rotates around 1 / 4 of the rotating shaft. The ball valve has extremely worried cutting off performance. When it is fully opened, its flow path is basically the same as the pipeline inner diameter, and the fluid pressure loss is very small. Therefore, it is most suitable for cutting off various liquids, gases and slurries.
