<br>The grade B type can be used to regulate water; however, the grade A type is only for pure water. Both product bodies are made of oil-free 316 stainless steel. Separately, there is also the WR110 series of small water regulators made of brass.<br>The SRH series catalog can be found here.

<br>We recommend setting 1 point to 0 MPa to exhaust the pressure immediately in the event of a malfunction.<br>Which preset pressure to set to 0 MPa depends on the user's device.

<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.
