NC Flow is intended for the control of heating and cooling systems. Incorrectly set flow is a common cause of low efficiency in installations.

Using NC Flow valves does not require special skills and they allow quick and easy adjustment of system output.

The NC Flow valve is equipped with a flow meter that measures the flow at all times. Made in Sweden.

The scale can be rotated - easy to read from all positions and the flow is visible even when the valve body is insulated. Since the liquid does not pass through the flow meter, the risk of contamination is eliminated and the flow can therefore be read for a long time after installation. The NC Flow manifold has a constant flow profile at the inlet. Therefore, only a straight piece of pipe with the same diameter and length as the manifold upstream of the inlet is required.
