Features of this product

Improved reproducibility of flow rate:Stable knob position when fully closed (zero flow rate) onto the contact face stopper (rotating stopper).
Minimal flow rate variation depending on the number of knob rotations.

Examples of mounting variations.

4 indicator window directions offer improved visibility.

Identification by index plate: It is possible to identify the product when multiple controllers are mounted and identify the flow direction by attaching an identification label.

Identification by color.

Flow rate can be controlled numerically with the indicator window.

In-line / Brass / Stainless steel
Larger push-lock type knob

Improves needle lock operation.

The larger knob and marking of every 90° mark allows for easier operation.
