VETUS vacuum operated vent valve, 56mm, for waste water tanks (VRF56A)

Description

This valve is an indispensable safety factor for emptying a waste water tank via shore-based pump-out a waste water tank is being emptied using a powerful shore-based pump-out station, one unfortunate possibility is that insufficient air might enter through the vent line, causing the tank to implode. To prevent this from happening, this VETUSvalve type VRF will automatically open with the increasing vacuum, thus letting air into the VRF56 has a free flow area of more than 1,100mm2 and thus fulfils the requirementsof the relevant ISO 8099 standard. The hole in the tank must be 56mm in diameter, which is the same size as the hole for a VETUS extraction valve is an indispensable safety factor if the vent line has a smaller diameter than19mm, or for tanks of more than 400lt, a vent line with a smaller diameter than 38mm. By using this valve, the necessity to fit a large-diameter vent line is avoided, thus saving cost and space whilst still meeting the ISO 8099 standard. This valve is made entirely from synthetic materials and is therefore absolutely corrosion-free.
