<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).
<br>While there were no major changes made, the product weight was reduced and tube detachability was improved. In addition, the KJ series was integrated into the new KQ2 series in accordance with the miniaturization of the series. <br>An additional seal type was also added. And in May 2015, a KQ2 series One-touch fitting with an oval release button was added.
<br>① KQ2E12-00□ (Bulkhead union) + KQ2R08-12A (Plug-in reducer)<br>② KQ2E12-03□ (Bulkhead connector) + KQ2H08-03□S (Male connector)

<br>By replacing the sleeve, you can block a pipe line. <br>The “Resin sleeve: KFS” is a part used for joining the tube to the insert part of the fitting body.
<br>Rotate the sleeve of the socket to lock and unlock it. The sleeve lock mechanism is available as standard for KK series S couplers and as an option for KK130 series S couplers. It is not available for KKA series S couplers. <br>Refer to the catalog for details. The KK series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=connectors&fa_id=10411
<br>Note 1) The same applies to the universal elbow and universal tee types. <br>Note 2) For elbow type One-touch fittings, the orientation of the piping section can be changed after the fitting is tightened.
