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.
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.
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...

⑫ The min. supply pressure is the min. required supply pressure for when there is no flow on the output side. If flow is to be used, or if the volume on the outlet side is large, supply pressure with sufficient margins in regards to the set pressure if responsiveness is required.
Caution ① Preparation before piping 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.
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...
(Note 1) When there is no flow rate on the outlet side. Maintain the minimum supply pressure (set pressure + 0.05MPa). (Note 2) Full span indicates the maximum set pressure of the product. (e.g.IR1000-A: 0.2MPa) (Note 3) Other characteristics such as aging deterioration and temperature characteristics are not included.
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 diaphragm as nozzle pressure. The force generated by the diaphragm pushes down the valve, and the supply pressure flows to the outlet.
4. How to order ― ― ― ・ Option/Semi-standard:Select one each for a to e. ・ Option/Semi-standard symble:When more than one specification is required, indicate in alphanumeric order. Symble Description 0.005~0.2MPa Set pressure range 0.01~0.4MPa 0.01~0.8MPa Pipe thread type Without pressure gauge Mounting With bracket With hexagon panel nut (for panel mount)
5. Bracket, gauge and switch assembly (optional) 1.Bracket 1) Installation of bracket (Grooved) Set nut Mount the bracket to the regulator as shown on the picture. Assemble so that the regulator and rotation stopper of the bracket align properly. 2) Holding with the set nut Bracket (Knurled tool face) Insert the set nut into the bonnet of the regulator so that the...
6.Panel mounting 1. Panel mounting 1) Handle removal Remove the handle from the regulator. 2) Panel mounting Insert the regulator into the panel. Handle 3) Nut tightening Adjust the regulator position and tighten the attached hexagon panel nut. Hexagon panel Recommended tightening torque Wrench size [mm] Tightening Torque[N-m]...
7.Troubleshooting Problem Possible causes Countermeasures Set the pressure again. Fluctuation of flow rate at the downstream side Return the flow rate at the downstream side to the initial rate. Moisture, condensate and foreign matter stuck to the Install a filter and/or mist separator to clean the air supply. flapper.
