Breather Valve TA225

TA225 Two-Way Pressure & Vacuum Relief Breather ValveThe TA225 is AGM's smallest aluminum Breather Valve. It is suitable for use on transit cases and other applications up to 2.5 cubic feet in volume. It has separate and distinct settings for both pressure and vacuum relief. Standard reseal settings range from 0.5 psid to 3.0 psid.

The TA225 requires no field maintenance. Corrosion-resistant materials are used throughout. The spherical valve seat is Teflon coated to allow for easy "break-away" action of the internal silicone rubber seal. The TA225 Breather Valve is offered with or without a manual release button and provides superior protection from sand and dust intrusion.

The TA225 can be mounted to a thru hole or threaded boss. Each valve comes complete with an environmental O-ring. An optional mounting flange and/or desiccant cartridge (up to 3" in length with choice of desiccant media) are available upon request. RFI/EMI shielded versions are also available.

Materials and Finish: Housing, nut and washer are aluminum alloys. Standard finish is clear anodizing. Gasket material is silicone per A-A-59588, Class II, Grade 40.

Weight: 0.02 lbs. (8 grams)

Mounting Requirements: Gasket, washer and hex nut are provided with each valve.
Mounting hole diameter: 0.55 ± 0.02 in. (14 ± 0.38 mm)
Installation torque: 20 in. - lbs. (2-3 N-m)
Maximum wall thickness: 0.33 in.(8.4 mm)
For threaded boss installation: 1/2-20 UNF-2B
