<br>This is why the power needs to be turned OFF.<br>When the source pressure is down, and the input signal to the regulator is 0% (0 MPa), the solenoid valve stops operating.

<br>The sum is ±0.011 MPa. This means that for the ITV2030, there may be a small difference between the actual output pressure and the displayed pressure, but it will be within ±0.011 MPa.<br>Note) The set pressure range of the ITV2030 is 0.005 to 0.5 MPa, 0 to 0.005 MPa is outside of the control range, and F.S. (full span) is 0 to 0.5 MPa.

<br>For AC-A/AC-B/AC-D series modular F.R.L. units, the regulator is from the AR-A/AR-B/AR-D series. <br>For the part number of the round pressure gauge, refer to the AR-A/AR-B/AR-D series catalog. The modular F.R.L. unit catalog can be found here.

<br>① Order the required products individually and assemble them yourself. To mount each attachment to the AC series modular F.R.L. unit, a spacer with a bracket is required separately. <br>② Fill out a “Simple Special Order Specification Form” (available for download from the SMC website) and submit it to your local SMC sales office to request assembly at the SMC factory.

<br>The limit indicator of the pressure gauge merely allows you to visually check the values and widths set for pressure management. <br>Consider adding a pressure gauge with a switch (GP46) or a pressure switch to output a signal.

<br>③ For the drain cock with a barbed fitting, a barbed fitting for piping tubing with an O.D. of 6 mm and an I.D. of 4 mm is provided below the drain discharge button. Drain (manually) through this tube to prevent drainage from splashing.

<br>The bracket mounting width and surface are interchangeable between old AC2 and older AC4 series products. <br>This product is a special product that combines old products and older products, and it is therefore not listed in the catalog.

<br>(the absolute pressure ratio = the actual inlet absolute pressure ÷ the inlet absolute pressure in the “Flow Rate Characteristics” graph in the catalog) <br>For example, when the inlet pressure is 0.7 MPa in the catalog, but it is actually 0.5 MPa, the formula is as follows: So use the flow rate value in the catalog graph x 0.75 as a guide.

<br>When the valve is energized (or the manual button is turned ON), low-speed air supply is performed with the flow rate adjusted by the needle valve, and when the pressure on the outlet side of the valve exceeds a certain level, the main valve is opened to provide high-speed air supply. <br>When the valve is turned OFF, the outlet air is rapidly exhausted from the exhaust port.

<br>Be sure to check the model and dimensions of the old AR series products to be replaced (e.g., AR40, AR4000, or AR410) so an appropriate substitute can be ordered. <br>The discontinued AR series catalogs can be found here.

<br>You can also mount Rc1/8 fittings and tubing and move the pressure gauge to another location. <br>Note) Do not apply pressure higher than the max. display pressure to the pressure gauge during pressure adjustment; otherwise, the pressure gauge may be damaged.

<br>The square embedded type pressure gauge and adapter assembly can be removed and replaced with a new pressure gauge adapter assembly and a round type pressure gauge. <br>Replace the inside O-ring with a new one. If the O-ring is not replaced at this time, air will leak.

<br>Compressed air is released from the gap around the knob to the outside through the relief hole provided in the center of the regulator’s diaphragm. <br>If this leakage occurs in situations other than that described above, the internal parts may be damaged or foreign matter may be clogging the product.

<br>Possible causes of low bowl pressure are as follows. ① The IN-OUT are reversely connected. ② There is leakage from the bowl O-ring. ③ There is leakage from the lubrication plug O-ring. Take appropriate measures.

<br>Oil may accumulate in the regulator, causing a large amount to flow from the outlet side temporarily. <br>Install the lubricator on the outlet side of the regulator to avoid this.

<br>The elements of the current product (AW□□-A/-B) are interchangeable with those of the old AW series (4 digits: AW□□□□). <br>Note) The old AW series (4 digits: AW□□□□) was released in 1986 and its element material was switched from sintered metal to non-woven fabric in 1996.

<br>Please consider switching to a product from the VBA20A/40A series. <br>Further details on discontinued products can be found here.

<br>If there is no leakage on the outlet side of the VBA series regulator, it is probable that the seal is worn due to internal leakage.<br>The VBA series operation manual can be found here.

<br>If 2 booster regulators of the same size are installed in series, the supply flow rate to the second VBA may be insufficient, and the pressure may not be increased to the required level.<br>If the use of 2 booster regulators in series is desired, assuming that the outlet flow rate will be 1/2 and 1/2, check whether a VBA40A followed by a VBA20A can be used.

<br>However, this is the old part number of a discontinued product.<br>It has been refreshed and replaced with the VBA43A-04** (standard).
