AVV3SSC: Chemical Air operated vapour vent, FFKM seals.
AVV3SSVG: Chemical Air operated vapour vent, Viton GFLT seals.
Liquip's AVV3SSxx is an air operated chemical vapour vent that
has been designed for superior chemical compatibility and
resistance.
The AVV3SSxx is a sequential vapour vent with the exhaust from the previous vent opening the next in line. The outlet from the last vent can be used via a pressure switch to activate the overfill protection system, once all vents are open.
It has a 90mm nominal diameter opening for reduced pressure drop and increased vapour flow during loading and unloading.
