The new Hora Automatic Recirculation Valve PSG-N from Austral Powerflo Solutions is designed to ensure  protection to centrifugal pumps from possible damage by thermal and hydraulic overloads at low flow rates.

An automatically controlled by-pass, regulates flow in these recirculation valves  to exactly correspond to the flow of the pump discharge. Under zero flow conditions, the main flow path is blocked by a non-return disc/valve, As demand for flow increases at the outlet of the PSG-N, the non-return valve begins to open, caused by the increase in pressure differential across the unit while the by-pass valve begins to close.

Low Noise single or or multistage pressure let down components guarantee accurate by-pass modulation control.
