The TA340-R HUMI-VALVE^® is a new design, incorporating a Humidity Indicator (not separately replaceable) and a two-way Breather Valve all in the same aluminum housing, thereby saving space and 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 0.5 to 3.0 scfm at 1.5 psid 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 25 cubic feet in volume.

Designed to accept a replaceable desiccant cartridge, this valve will mate with the 658800 Mounting Flange for ease of desiccant replacement. Desiccant cartridges are available in lengths of up to six inches and hold approximately 6.5 grams (0.23 ounces) per inch of cartridge.  There is a separate air path to the Humidity Indicator, bypassing the desiccant cartridge.  IMPORTANT: The installation of the desiccant cartridge will reduce the available flow rate for a given pressure setting.  The valve can also be supplied in RFI/EMI shielded versions.

The TA340-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 TA340-R Breather Valves.  It is used to equalize residual pressure or vacuum differentials in order to make opening the container easier.  Gasket, washer and hex nut are provided with each valve.

Materials and Finish: Housing, nut and washer are aluminum alloy with clear anodize finish.  Gasket is silicone rubber per ZZ-R-765.  Window is high strength plastic.  Torque value for installation: 30 in. - lbs. (3.4 N•m)  Weight: 0.09 lbs. (40 grams)
