Safety Instructions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act. - Page 5 Operating Environment Warning ① Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. ② Do not operate in locations where vibration or impact occurs. ③...
- Page 6 ⑫ When using the IR3000-A series in balancing applications, abnormal noises may occur depending on the pressure and circuit conditions. In such cases, the noise will often cease if changes are made to the pressure or piping conditions or if a high noise reduction type silencer (such as SMC’s ANA1 series, etc.) is installed.
- Page 7 Caution Preparation before piping ① Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. ② Winding of sealant tape When screwing piping or fittings into ports, ensure that metal chips from the pipe threads or sealing material do not enter the piping.
- Page 8 Maintenance Warning ① When the product is removed for maintenance, reduce the set pressure to “0” and shut off the supply pressure completely beforehand. ② When a pressure gauge is to be mounted, remove the plug after reducing the set pressure to “0”. ③...

１． Application This instrument aims at controlling pressure of air lines. ２． Specifications Model IR300(0,1,2)-A IR301(0,1,2)-A IR302(0,1,2)-A Max. supply pressure [ MPa] Min. supply pressure Set pressure + 0.1 (Note 1) [MPa] Set pressure range 0.01 to 0.2 0.01 to 0.4 0.01 to 0.8 [MPa] (Note 2) - Page 10 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.
