 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)
Mounting Requirements: Gasket, washer and hex nut are provided with each valve.
Mounting hole diameter: 1.05 ± 0.015 (27 ± 0.38 mm)
Installation torque: 30-40 in. - lbs. (3.4-4.5 N•m)
Maximum wall thickness: 0.61 (15 mm)
Add extra washer for wall thickness less than 0.025 (0.64 mm). (AGM P/N 300013-16, order separately.)
For threaded boss installation: 3/4-14 NPSM; no counterbore requirement.
