<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.
<br>KQ2□-□A fittings are listed in the KQ2-G series catalog. <br>Please refer to the catalog for details. The KQ2-G series catalog can be found here.
<br>The leakage amount is the same for all 3 types. However, in terms of pull-out strength, it can be said that KFG2 series insert fittings are strongest. <br>(The pull-out strength of KQG2 and KQB2 series fittings is the same.)
<br>Note) The bellows are replaceable. Be sure to order with the bellows assembly for ISG series pressure switches.
