The TA330 Breather Valve is tamper-proof and requires no field maintenance.
Corrosion-resistant materials are used throughout. The valve seal is made of
silicone rubber. The spherical valve seat is Teflon coated
for easy "break-away" action even after prolonged storage. Gasket,
washer and hex nut for mounting are provided with each valve. A
weldable nut is available for use as a threaded boss, or the
valve may be used with our 658800 Mounting Flange. RFI/EMI shielding is also available. For additional enclosure protection, AGM can develop a custom desiccant cartridge that mates with the valve.
The TA330 Breather Valve's unique cover and dust baffle provides superior protection from sand and dust intrusion. Additionally, the cover makes this valve well suited for high-pressure hose down applications. When compared to a screened valve such as AGM's TA238 Breather Valve as well as competitors' valves, the TA330 Breather Valve allows virtually no water to pass when subjected to a high-pressure water stream. The TA330 Breather Valve has been tested to the NEMA 250 5.7 high-pressure hose down test; contact AGM's Engineering department for more information.
Materials and Finish: Housing, nut and washer are aluminum
with anodized finish. Gasket
material is per ZZ-R-765, Class II, Grade 60. Torque value
for installation: 30 in. - lbs. (3.4 N•m) Weight:
.10 lbs. (45 grams)
Mounting Requirements: Gasket, washer and hex nut for mounting are provided with each valve. A weldable nut is available for use as a threaded boss, or the valve may be used with our 658800 Mounting Flange.
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: 0.57 (14 mm)
Add extra washer for wall thickness less than 0.063 (2 mm). (AGM P/N 300013-16, order separately.)
For threaded boss installation: 3/4-14 NPSM; 1.05 ± 0.015 (27 ± 0.38 mm) diameter X 0.11 (3 mm) minimum deep counterbore required for thread relief.
