Filler Valve TA322

The TA322 Filler Valve provides a tire valve core in a lightweight minimum length housing. This valve may be used to purge or pressurize containers. A stainless steel version, the TA322-SS is also available. See NEPS 1000 to learn more about AGM's nitrogen and dry gas purge systems.

An air chuck is required to actuate valve (not furnished by AGM). The cap may be secured to the housing by a user-supplied safety wire.

Due to threading limitations approaching the hex flange, when using in a threaded boss, a 0.385 ± 0.010 (9.75 ± 0.25 mm) diameter X 0.10 (2.5 mm) minimum deep counterbore is required for thread relief. In addition, also for threaded boss installation, we recommend a countersink or a counterbore be used to capture the o-ring seal. For countersink, we recommend a 90° countersink with .560-.540 diameter. For an o-ring counterbore, we recommend that it be .560 ± .010 diameter X .063-.048 deep.

The TA322 is appropriate for use on NEMA 1, 2, 3, 3R, 3S, 4, 5, 6, 12, 12K, and 13 enclosures, as well as IP65/IP67 enclosures. This item may also be appropriate for use on other NEMA or IP enclosures, depending upon the application. Contact AGM's Engineering department for more information.
