Features
- The transparent tapered tube allows you to see the flow rate at a glance so you can check the approximate flow rate by looking at the relative position of the ball (or float) and the red line.
- The required flow rate can be set by adjusting the miniature valve with flow control valve and aligning the ball (or float) with the red line .
- The installation direction is not important .
- A spring is used inside, so the installation direction can be freely changed, such as upward, downward, or sideways.
