Options/Part No.
Note 1) Assembly of a bracket and set nuts
Note 2) 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 specifi cations.
Note 3) Standard pressure gauge
Note) Use a bushing (part no: 131368) when connecting the R1/8 pressure gauge to the Rc1/16.
Specifi c 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 backfl ow function.
Warning
Maintenance
1. When using the regulator between a solenoid valve and an ac-
tuator, check the pressure gauge periodically. Sudden pres-
sure fl uctuations 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 in-
let and outlet pressure gauges. Turning the regulator knob ex-
cessively 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 fl uctuate.
• 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 disap-
pear).
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. Refer to the back cover for Safety Instructions, “Handling Precautions for
SMC Products” and the Operation Manual for F.R.L. Precautions, http://www.smc.eu
