Definition of Low-Pressure Back-pressure Regulator

Low-Pressure Back-pressure Regulators can stabilize pipeline pressure, provide a stable back pressure for the system, and improve material dosing accuracy; Micro-pressure Back-pressure Regulators adopt a large diaphragm cover balancing structure, featuring stable pressure control and high precision, and are used in low-pressure liquid and gas pipelines.

Working Principle of Low-Pressure Back-pressure Regulator

Back-pressure Regulators work by the elastic force of the spring. When the system pressure is lower than the set pressure, the diaphragm blocks the pipeline under the action of the spring's elastic force; when the system pressure is higher than the set pressure, the diaphragm compresses the spring, the pipeline is connected, and the medium passes through the Back-pressure Regulator.
