Stainless Steel Air Operated Vapour Vents
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.
Features & Benefits
- Adjustment free.
- Low maintenance.
- 90mm nominal diameter opening for minimum full 80mm flow throughout.
- Piston operation for sequential operation.
- Downward opening poppet to prevent leaks from product surge, in the event of a tanker rollover.
- The sequencing valve is offered to ensure the main poppet is fully open before next vent opens.
- The end signal can then be used to allow loading/unloading in the certainty that all vapour vent poppets are open.
- Air cylinder is serviceable without removing the valve from tank.
