Breather Valve TA294-R

TA294-R Two-Way Pressure & Vacuum Relief Breather ValveThe TA294-R Breather Valve was designed to meet the need for a low cost, two-way valve for use on transit cases and similar applications up to 8 cubic feet in volume.  It is similar to TA292-R Breather Valves, except it is longer and has a flow rate of 1.0 scfm at a pressure of 1.5 psi to 2.0 psi above the valve setting.  Standard settings range from 0.5 psid to 3.0 psid reseal pressure.

The valve is tamper-proof and requires no field maintenance.  Corrosion-resistant materials are used throughout.  The valve seal is made of silicone rubber.  Each valve comes complete with a nut, washer and gasket.  A manual release push button is standard on all TA294-R valves.  It is used to equalize pressure or vacuum differentials in order to open the container.

Materials and Finish: Housing, hex nut and washer are aluminum alloys. Standard finish is alodine, except for the hex nut, which is anodized. Gasket material is per AMS-R-6855, Class II, Grade 60. Torque value for installation: 25 in. - lbs. (3.0 N•m)  Weight: 0.02 lbs. (32 grams)

Mounting Requirements: Each valve comes complete with a nut, washer and gasket.
Mounting hole diameter: 0.78 ± 0.015 (20 ± 0.4 mm)
Installation torque: 25-35 in. - lbs. (3.0-4.0 N•m)
Maximum wall thickness: 0.10 (3 mm)
Minimum wall thickness: 0
For threaded boss installation: 0.750-16 UNF-2B; no counterbore requirement
