non-return valve

Non-return valve

Flow regulator

The groups of pumping solar present CHARACTER important that enhance the stability of the system, such as the presence of a practical flow regulator that allows a smooth operation of the plant.

This fact shows the taps of loading / unloading in a close position, thus minimizing the residual air in circulation after the loading operation.
