The Auto Limiter II overfill protection system is an automatic
shut-off valve designed to be installed in the
4" riser pipe of underground storage tanks with tight fill
adaptor to reduce the flow by 90% at first stage
(approximately 92% of tank capacity) and shut down the gravity
flow at 95% of tank capacity. It is designed
to be installed in a spill containment manhole, which makes
it unnecessary to break concrete or add a new
manhole. The anodized cast aluminum valve body and aluminum
drop tubes make the Auto Limiter II
virtually maintenance free. The Drain Valve Isolation Kit(708-255-01)should
be used in a retrofit upgrade
to comply with CARB EVR requirement.
Features
1. Faster deliveries with less restriction
2. Can be set to 99% of tank capacity
3. Overfill protection at a field-set level
4. Two stage flow shut down provides reduced line shock compared
to competitive models. First stage reduces flow by 90%, Second
stage shuts off remaining 10%
5. Accommodates all tank sizes
6. Easy field installation without breaking concrete
7. Enables manual stick gauging of tank after a complete shut-off
