 The
TA240-R is a hybrid of the TA333-R Breather Valve and TA238 Breather Valve. It
combines the mounting thread size and hex shape of AGM's TA333-R Breather Valve
with the screened cover and lower cost of AGM's TA238 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 1.5 to
4.0 scfm at 1.5 psid above the reseal setting and is available
in settings from 0.5 psid to 5.0 psid.
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 TA240-R
Breather Valves. It is used to equalize residual pressure or vacuum
differentials in order to open the container. Gasket, washer
and hex nut are provided with each valve. A mounting
flange and RFI/EMI
shielding are available for this valve. As
indicated below, the lower the setting, the higher the flow rate.
The TA240 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.
Materials and Finish: Housing, washer and hex
nut are aluminum alloy. Housing is black anodize finish. Washer
and nut are clear anodize finish. Other
finishes available upon request. Gasket is silicone rubber
