TA238 Breather Valve fills the need for a low cost, but higher
flow valve than the TA294-R Breather Valve. The valve can be used on transit
cases and similar applications up to 33 cubic feet in volume. It
has a flow rate of 4.0 scfm and is available in settings from
0.5 psi to 5.0 psi.
The 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
recessed manual release push button is standard on all TA238 Breather Valves. It
is used to equalize residual pressure or vacuum differentials
in order to open the container.
The TA238 Breather Valve will not provide protection against water intrusion from a high-pressure hose down. Use a TA330, TA333 or TA770 Breather Valve for applications where this is required.
The valve is identical in dimensions, materials and performance
to the Zero ZSP6-037 Breather Valve. An o-ring gasket and
hex nut are provided with each valve. RFI/EMI shielding
Materials and Finish: Housing and hex nut are
aluminum with black anodize finish. O-ring is per MS28775-120. Torque
