1.[ Pressure Control]Effectively reduces water pulsation from coffee machine's electromagnetic pump, mitigates pipeline vibrations, and counteracts any adverse impacts on coffee brewing 2.[Flow Rate Control]Electromagnetic pumps in coffee machines typically produce a more continuous water flow compared to vibration pumps. However, to fine-tune the flow rate and maintain consistency, a stabilizing flow valve is added at the electromagnetic pump's outlet. This valve enables precise adjustment of the water flow rate, aiding in controlling the saturation of the coffee grounds and extraction [3.Pressure Stabilization]While electromagnetic pumps generate a more consistent water flow, there can still be slight variations in pressure. The stabilizing flow valve helps stabilize and regulate these minor pressure fluctuations, ensuring a steady and even water pressure during the entire extraction process. This contributes to uniform coffee extraction. fit for /// Note: Installation guide not included, Please check as much as possible to make sure the item is what you need.
