Q341F worm gear floating ball valveDetailed product description：

summary:
Q341F worm gear floating ball valve is an important type of valve, widely used in fields such as petrochemicals and long-distance pipelines. The closing element of a ball valve is a ball (or partial ball) with a hole, which rotates with the valve stem to open or close the valve.

Among various valves, ball valves have the lowest flow resistance. When a full diameter ball valve is opened, the ball channel, valve body channel, and connecting pipe diameter are equal and form one diameter, allowing the medium to flow almost without loss.

The ball valve can be fully closed and fully opened by rotating 90 degrees, with quick opening and closing. Compared with gate valves and globe valves of the same specifications, ball valves have a smaller volume and lighter weight, making them easier to install in pipelines.
