Product Overview
The SMC AR30-02B 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: an adjusting knob compresses a control spring, which acts against a diaphragm to position the internal valve poppet, thereby maintaining the set outlet pressure regardless of fluctuations in inlet pressure or flow demand. The AR30-02B features a 3/8″ port size (02) with a relieving (B) configuration, allowing excess downstream pressure to vent automatically when the set pressure is reduced. This regulator serves as a critical control element in pneumatic circuits, protecting downstream actuators, cylinders, and instrumentation from over-pressurization while ensuring consistent operating pressure for optimal system performance.
