The automatic recirculation valve includes a decompression facility for recirculation flow, so that the high pressure medium flows through many small channels, consumes a lot of energy, and reduces the pressure.

This valve only has recirculation when the flow rate is very low, so that the pump is cooled, and when the pump is running normally, there is no recirculation, which can save the electricity and water energy consumed by continuous recirculation.

Automatic recirculation control valves do not require electrical wiring, nor do they require two in series, one for regulating and the other for cutting. And the high speed flow line and erosion phenomenon easily produced by the high pressure system to minimize.

This product has the advantages of reasonable design, smooth operation, no noise, long life, etc., and can completely replace imported products.
