Abstract
A vapor pressure equalizing valve disposed in a vapor return conduit between a storage tank and a liquid receiving tank to provide the same volume of flow but at a higher rate and greater fluidity than that of liquid flow volume in a preferably larger liquid conduit, and providing an excess flow shut off response that can be triggered manually or by the danger of a hose rupture or in case of fire or a break in the vapor return conduit, to protect either tank, or with two valves protect both tanks, with great quickness of action. The valve serves as a manual vapor flow shut off valve which may be latched open; and is unlatched to close by a local or remote control or fire, but while latched open provides an excess flow arresting action.
