 The
TA333-R Breather Valve has separate and distinct settings for
both pressure and vacuum relief. It has a flow rate that ranges
from 1.5 to 4.0 scfm at 1.5 psi above the valve reseal setting, making
it suitable for containers and similar applications up to 33 cubic
feet in volume. Standard settings are available from 0.5
psid to 3.0 psid reseal pressure. The lower the setting,
the higher the flow rate.
The TA333-R 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. The
manual release push button is used to equalize the pressure or
vacuum differentials in order to make opening the container easier. The
button is recessed in the cover to protect it from damage and
eliminate the possibility that an adjacent container might press
the button and inadvertently cause the valve to remain open. A
unique feature of the push button is a light duty spring under
the cover, separating the button from the vacuum stem, which
must be overcome before the button opens the valve.
Gasket, washer and hex nut 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 TA333 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 TA333 Breather Valve allows virtually no water to pass when subjected to a high-pressure water stream. The TA333 Breather Valve has been tested to the NEMA 250 5.7 high-pressure hose down test; contact AGM's Engineering department for more information.
