 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)
Mounting Requirements: A gasket, washer and hex nut are provided with each valve.
Mounting hole diameter: 1.265 ± 0.015 (32 ± 0.3 mm)
Installation torque: 30-40 in. - lbs. (3.4-4.5 N•m)
Maximum wall thickness: 0.38 (10 mm)
