The TA440-R HUMI-VALVE^® incorporates a Humidity Indicator and a two-way Breather Valve all in the same housing, thereby saving the cost of an additional hole in the case.  The valve has separate and distinct settings for both pressure and vacuum relief.  It has a flow rate of 4.0 scfm at 1.5 psi above the valve setting.  Standard settings are from 0.5 psid to 3.0 psid reseal pressure.  The lower the setting, the higher the flow rate, making this valve suitable for transit cases and similar applications up to 33 cubic feet in volume.

There is a separate path to the Humidity Indicator.  The TA440-R Breather Valve is lightweight, rugged, tamper-proof and requires no field maintenance.  Corrosion-resistant materials are used throughout.  The valve seal is made of silicone rubber.  A manual release push button is standard on all TA440-R Breather Valves.  It is used to equalize residual pressure or vacuum differentials in order to make opening the container easier.  A gasket, washer and hex nut are provided with each valve.

Materials and Finish: Body and hex nut are black polycarbonate plastic.  Washer is aluminum alloy.  Humidity Indicator housing is high strength clear plastic.  Gasket material is per AMS-R-6855, Class II, Grade 60.  Torque value for installation: 30 in. - lbs. (3.4 N•m)  Weight: 0.09 lbs. (40 grams)
