Product Overview
The SMC AR30-02-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-loaded poppet principle: an adjustment knob compresses a regulating spring against a diaphragm, which modulates the internal valve seat to maintain the set outlet pressure regardless of fluctuations in inlet pressure or flow demand. The AR30-02-A features a 3/8″ port size (02 designation) with Rc (PT) threaded connections and an integrated pressure gauge, making it a direct-fit solution for industrial pneumatic circuits requiring accurate pressure regulation and reliable performance in continuous duty applications.
