- Page 6 Piping Warning ① 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 Caution ① 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 Warning ① The operating fluid must be compressed air. Contact SMC if using the product with other fluids. ②...
- Page 8 (Note 1) When there is no flow rate on the outlet side. Maintain the minimum supply pressure (set pressure + 0.1MPa). (Note 2) Full span indicates the maximum set pressure of the product. (e.g.IR3000-A: 0.2MPa) (Note 3) Other characteristics such as aging deterioration and temperature characteristics are not included.
- Page 9 ３． 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.
