Maeda Koki MKT Type Air Signal

Made in Japan
 Manufacturer: Maeda Machinery Research Institute Ltd.
 Model: MKT Type
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 installation direction is not important.
- The spring is used inside, so the installation direction can be freely changed, such as upward, downward, or sideways.
- *The standard specification flow rate is a guideline. Please be sure to let us know the actual flow rate you will be using.
