Auto Limiter Automatic Shut-Off Valve
The Auto Limiter Ioverfill 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 *0% at first stage
(approximately *2% of tank capacity) and shut down the gravity flow
at *5% 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(*********1)should be used in a
retrofit upgrade to comply with CARB EVR requirement.
