Overfill Prevention Valve and Fill Tubes

The EMCO Guardian Overfill Prevention Valve is a two stage overfill prevention valve which features an internal float design that eliminates any chance of the float getting caught on the tank walls or the riser pipe.  This design also prevents float damage during installation.   

The EMCO Guardian Overfill Prevention Valve is supplied pre-assembled to the aluminium fill tube for ease of installation.  Once the tank type and location of the Fill Isolation Valve is known, the fill tube is manufactured to ensure the valve cuts off at the correct height, normally 95% of the tank capacity.   

The fill tube can also be supplied without an Overfill Prevention Valve and with or without a deflector.
