Description

CARB approved and UL-listed Defender Series overfill prevention valve (OPV) prevents the overfill of a fuel underground storage tank during a gravity-fed product delivery. It employs a magnetically-coupled actuator system to provide positive shutoff. This unique method of shutoff eliminates any penetrations in the valve, making it both vapor and leak tight. The Defender Series OPV provides safe, rapid, and reliable fuel drops with simple installation, service, and remote testing capability.
