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.
