Introducing Non-Retention 2-Piece Ball Valve for Reliable Flow Control

Introducing Non-Retention 2-Piece Ball Valve for Reliable Flow Control

2025-06-20

The non-retention 2-piece ball valve is a common valve type, mainly used for fluid control. Its design features two main components (valve body and ball), with a through hole in the ball, which can open and close the fluid when the ball rotates. The non-retention design means that when the valve is closed, the fluid will not be retained inside the valve, thereby reducing the retention time of the fluid and the possible risk of contamination.
