This combination of characteristics makes it ideal for large enclosures such as military shelters or large shipping\/storage containers that require protection from the pressure differentials that arise from air transport, daily variation in temperature and atmospheric pressure, and the opening and closing of the enclosure door. The TA820 features a flip-open cover with a micro-louvered aluminum screen. Releasing the two quarter-turn fasteners allows the cover to flip open for manual pressure and vacuum relief or inspection of the valve internals. The TA820 breather valve will protect against rain, but not against water intrusion from a high-pressure hose down. For solid wall applications (-S), the valve is provided with a spanner nut and washer. For thick, hollow wall applications, the body of the hollow wall nut (-H) recesses into the wall, presenting a nearly flush surface on the inside of the container. The perforated aluminum screen on the hollow wall nut prevents interference with the valve internals, and provides some RFI\/EMI shielding. Where needed, AGM can provide a fully RFI\/EMI shielded solution. For applications where particle ingress is a concern, filtration is also available. Please contact AGM for details. Before making drawings of these valves, contact AGM for part numbers to be used. PRESSURE SIDE (FLOW OUT)* VACUUM SIDE (FLOW IN)* Crack Reseal Min. Flow Crack Reseal Min.
