Product Overview
The SMC AR20-02-A is a precision pneumatic pressure regulator from the SMC AR series, engineered to deliver stable, repeatable downstream pressure control in compressed air systems. As a process and pneumatic valve component, it operates on a diaphragm-actuated, spring-balanced regulating principle: the adjusting knob compresses a control spring, which acts against a diaphragm to modulate the internal valve poppet, maintaining the set outlet pressure regardless of fluctuations in inlet pressure or flow demand. The AR20-02-A features a 1/4″ port size and is designed for panel or bracket mounting, making it a compact and reliable solution for point-of-use pressure regulation in industrial automation, pneumatic control panels, and process equipment. Its relieving-type design allows excess downstream pressure to vent, protecting sensitive downstream components from over-pressurization.
