Breather Valve TA289


The TA289 is one of AGM's smallest Breather Valves. It was designed to meet the need for smaller packages requiring a two-way valve. For use on transit cases and similar applications up to 5 cubic feet in volume. The TA289 Breather Valve has separate and distinct settings for both pressure and vacuum relief. It has a flow rate of 0.6 SCFM at a pressure of 3.5 psi to 4.0 psi above the valve setting. Standard settings range from 0.5 psid to 3.0 psid reseal pressure.

The valve requires no field maintenance. Corrosion- resistant materials are used throughout. The valve seal is made of silicone rubber.  Intended for use in threaded bosses, each valve comes complete with an environmental o-ring. An optional mounting unit is available upon request. May also be supplied with an optional desiccant cartridge up to 3" in length with a choice of desiccant materials. RFI versions are also available.
