Breather Valve TA240-R

Meets SAE Specification AS27166 & MIL-DTL-27166

TA240-R Two-Way Pressure & Vacuum Relief Breather Valve with Recessed Manual Release Push ButtonThe 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.  As indicated below, the lower the setting, the higher the flow rate. Mounting Flanges and RFI/EMI shielding are available for this valve.  For additional enclosure protection, AGM can develop a custom desiccant cartridge that mates with the valve.

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 per ZZ-R-765.  Torque valve for installation: 30 in. - lbs. (3.4 N•m)  Weight: 0.02 lbs. (32 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 .04 (1 mm). (AGM P/N 300013-16, order separately.)
For threaded boss installation: 3/4-14 NPSM; 1.05 ± 0.015 (27 ± 0.38 mm) X 0.08 (2 mm) minimum deep counterbore required for thread relief.
