VETUS Vacuum Valve 56 Mm Diameter For Waste Water Tanks

To prevent this possibility, this VETUS valve type VRF will
automatically open with the increasing vacuum, thus letting air
into the tank.

Model VRF 56 has a free flow area ofmore than 1100 mm2 and thus
fulfils the requirements of the relevant ISO 8099 standard.The hole
in the tank must be diameter 56 mm, which is the same size as the
hole for a VETUS extraction pipe.

This valve is an indispensable safety factor if the vent line has a
smallerdiameter than 19 mm, or for tanks of more than 400 litres, a
vent line lessthan 38 mm. By using this valve, the necessity to fit
a large diameter ventline is avoided, thus saving cost and space
whilst still meeting the ISO 8099standard. This valve is made
entirely from synthetic materials and thereforeabsolutely
corrosion-free.
