Page 5: Specifications
Foreword The IR2120 precision regulator (hereinafter referred to as the “product”) has excellent relief characteristics, and is constructed to always keep a constant pressure even if used with a reverse flow. The product has the following features. (1) A sensitivity of 0.2%F.S. at max is achieved by the nozzle and flapper design. - Page 6 The downstream side flow rate is zero. (Note 4)The F.S. means the condition at the maximum setting pressure of the product. (F.S. ≒0.8MPa, IR2120) (Note 5) Repeatability: This is the reproducibility of the downstream pressure at every operation (ON/OFF) on the downstream side.

Page 7: Construction And Operation Principle
2. Construction and operation principle When the input signal from regulator and instrument is risen, ②flapper closes the ③nozzle by the generated force of ①diaphragm(A), allowing the supply air that flows in from the upstream side to pass through the ④fixed orifice. It then acts on ⑤diaphragm(B) as nozzle back pressure, the ⑥main valve is pushed down by the generated force and the supply pressure flows out to the downstream side.The air pressure that flows in acts on ⑦diaphragm(C) and while opposing the force generated by ⑤diaphragm(B),it also acts on ①diaphragm(A ) and balances at the set pressure which is opposing... -

Page 9: Precautions For Handling
5. Precautions for handling Fluid Warning (1) Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction. (2) If the drain removal from air filter and mist separator is missed, drain will be flown out to the outlet side and may result in a malfunction of the pneumatic equipment. - Page 10 Maintenance Warning (1) When the valve guide (refer to construction drawing on page 6) is to be removed during maintenance, first reduce the set pressure to “0” and completely shut off the supply pressure. (2) When a pressure gauge is to be mounted, remove the plug after reducing the set pressure to “0”.
- Page 11 (2) Do not apply torsion or bending moment other than the weight of the product itself. The external piping should be supported separately because it may cause breakage. (3) Non-flexible piping such as steel piping will be subject to excessive moment load and vibration from the piping side, so use a flexible tube for intermediate connection.
- Page 12 Operation Warning (1) Do not use a precision regulator outside the range of its specifications as this can cause failure.(Refer to the specifications.) (2) When mounting is performed, make connections while confirming port indications. (3) Screw a panel nut with the recommended proper torque 21N･m when mounting onto a panel.

6. Warranty (1) Period: The warranty period of the product is 1 year in service or 1.5 years after the product is delivered, whichever is first. (2) Scope: For any failure or damage reported within the warranty period which is clearly our responsibility, a replacement product or necessary parts will be provided. -
