SMC Compact Piston Air Regulator with Rc 1/8 Ports and Bracket
About this part
SMC ARX20-01B is a compact, relieving piston regulator for compressed-air pressure control. This configuration provides a 0.05 to 0.85 MPa regulating range, Rc 1/8 connections, and the B mounting-bracket option. Maximum operating pressure is 2.0 MPa. The B option includes a panel nut; no pressure-gauge option is encoded
Configurations vary. Verify the exact unit before choosing a replacement.

Installation and Service Notes
Set pressure while increasing from a lower pressure, then lock the adjustment knob.
Connect the air supply to the port marked SUP; reversed connections can cause malfunction.
Outlet pressure may remain after inlet pressure is relieved at a low outlet setting. Provide a residual-pressure relief circuit where reliable downstream exhaustion is required.
Flush piping before connection and prevent thread chips or sealing material from entering the air path.
Use clean compressed air and remain within the documented pressure and temperature limits.
