Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.”They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations. - Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
- Page 5 Operating Environment Do not use in an atmosphere containing corrosive gases, chemicals, organic solvent, sea water, water, water steam, or where there is direct contact with any of these. Do not operate in environments subject to heavy vibration and/or impact. The regulator should not be exposed to prolonged sunlight.
- Page 6 Piping Connect piping/fittings using the recommended torque while holding the product tightly. Looseness or faulty sealing will occur if tightening torque is insufficient, while thread damage will result if the torque is excessive. Furthermore, if the side with the female threads is not held while tightening, excessive force will be applied directly to piping brackets, etc.
- Page 7 Handling When the precision regulator with pressure gauge is used, do not apply impact to the product by dropping it etc. during transportation or installation. This may cause misalignment of the pressure gauge pointer. Air Supply The operating fluid must be compressed air. Contact SMC if using the product with other fluids. Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salts or corrosive gases etc., as this can cause damage or malfunction.

Application This instrument aims at controlling pressure of air lines. Specifications Model IR320(0,1,2)-A IR321(0,1,2)-A IR322(0,1,2)-A Max. supply pressure [ MPa] Min. supply pressure Set pressure + 0.1 (Note 1) [MPa] Set pressure range 0.02 to 0.2 0.02 to 0.4 0.02 to 0.8 [MPa] (Note 3) (Note 2) -
Page 9: Construction And Operation Principles
Construction and Operation Principles When the knob is rotated, the flapper is pushed through the spring, and a gap is generated between the nozzle and flapper. The supply pressure flows to the inlet passes through the path between the nozzle and flapper and acts on the supply / exhaust diaphragm as nozzle pressure. The force generated by the diaphragm pushes down the valve, and the supply pressure flows to the outlet. -
