Original Press Release:

Breather Valve Updates Include 'Enviro-sealed' and Low-Cost Models

Tucson, AZ. Design updates in AGM Container Controls' range of two-way pressure and vacuum relief breather valves include model TA333-R, which is specially weather-shielded for long-term shipping or storage containers where worldwide environmental and weather variations are encountered, and the low-cost TA238, which has a perforated metal cover suitable for transit cases or other applications not facing such conditions.

Both tamper-proof models feature recessed manual release push buttons that equalize pressure or vacuum differentials, use corrosion-resistant materials throughout and require no field maintenance. They protect encased equipment from the effects of moisture and pressure/vacuum differentials due to temperature and/or altitude changes by effectively providing "controlled breathing" and automatically adjusting container pressure.

The TA333-R breather valve's weather-shielding cover and dust baffle give unique protection against sand, dust and water intrusion into the container or enclosure. It has separate and distinct settings for both pressure and vacuum relief and is suitable for containers up to 33 ft³ in volume, as well as for electronic or other sealed enclosures. Standard settings are available from 0.5 psid to 3.0 psid reseat pressure and flow rate ranges from 1.5 to 4.0 scfm at 1.5 psi above the valve reseal setting.

The TA238 valve fills the need for a low cost unit with a perforated metal cover, but higher flow than previous similar models. It can be used on transit cases and similar applications up to 33 ft³, has a flow rate of 4.0 scfm and is available in settings from 0.5 psi to 5.0 psi.

These low-pressure high-flow valves meet SAE Specification AS27166 and are available with RFI/EMI shielding. Their manual release buttons feature a unique light duty spring under the cover, separating the button from the vacuum stem, which must be overcome before the button opens the valve. RFI/EMI shielding is available.

The TA333-R is supplied with a gasket, washer and hex nut. A weldable nut is available for use as a threaded boss and the valve may also be used with a mounting flange. The TA238 comes with an o-ring gasket and hex nut.
