56 Regulator Series AR10-A to AR40-A AW AL AR AFM / AFD AF Attachment AW+AFM AF+AFM+AR AF+AR AW+AL AF+AR+AL AC Standard Specifications Options/Part No. Note 1) Assembly of a bracket and set nuts Note 2) l in round pressure gauge part numbers indicates a pipe thread type. No indication is necessary for R; however, indicate N for NPT. Please contact SMC regarding the pipe thread type NPT and the supply of pressure gauge with psi unit display specifications. Note 3) Standard pressure gauge Note) Use a bushing (part no: 131368) when connecting the R1/8 pressure gauge to the Rc1/16. Specific Product Precautions Selection 1. Although exhaust of the residual pressure to the inlet side is possible when eliminating the inlet pressure, exhaust is not possible when the set pressure is 0.15 MPa or less. Use the regulator with backflow function. Warning Maintenance 1. When using the regulator between a solenoid valve and an actuator, check the pressure gauge periodically. Sudden pressure fluctuations may shorten the durability of the pressure gauge. A digital pressure gauge is recommended for such situation or as deemed necessary. Warning Mounting/Adjustment 1. Set the regulator while verifying the displayed values of the inlet and outlet pressure gauges. Turning the regulator knob excessively can cause damage to the internal parts. 2. Do not use tools on the pressure regulator knob as this may cause damage. It must be operated manually. Warning 1. Be sure to unlock the knob before adjusting the pressure and lock it after setting the pressure. Failure to follow this procedure can cause damage to the knob and the outlet pressure may fluctuate. . Pull the pressure regulator knob to unlock. (You can visually verify this with the “orange mark” that appears in the gap.) . Push the pressure regulator knob to lock. When the knob is not easily locked, turn it left and right a little and then push it (when the knob is locked, the “orange mark”, i.e., the gap will disappear). 2. Pulsation will be generated when the difference between the inlet and the outlet pressure is large. In this case, reduce the pressure difference between the inlet and the outlet. Please consult with SMC if the pulsation problem is not resolved. Caution Be sure to read this before handling.
