The AMF Vapour Transfer Adaptor forms part of the equipment (in conjunction with the vapour transfer valve and vapour transfer coaming valve) to ensure the closed transfer path by connecting the vapour system from the road tanker directly to the loading/off-loading facility. The Vapour Transfer Adaptor allows for a vapour tight path between the transport tank, petrol storage tank, service station tank, and the vapour recovery unit during the loading and unloading operations. Opening and closing of the valve is automatic and linked to the pneumatic loading and off-loading controls of the road tanker for error free operation. Most commonly used in the petro-chemical industry, this valve is gaining popularity as safety and environmental concerns become increasingly important.
