Abstract
A system including a vapor recovery valve having a valve body with a fluid flow path and a vapor flow path. The fluid flow path and the vapor flow path are generally fluidly isolated from each other. The vapor recovery valve further includes a vapor control valve positioned in the vapor flow path. The vapor control valve is movable between a first position wherein the vapor control valve at least partially impedes the flow of vapor therethrough and a second position wherein the vapor control valve does not impede or less impedes the flow of vapor therethrough compared to when the vapor control valve is in the first position. The vapor recover valve includes an actuator magnetically coupled to the vapor control valve. The actuator is configured such that sufficient fluid flow through the fluid flow path in a first direction causes the actuator to move the vapor control valve from the first position to the second position in a second direction that is generally not the same as the first direction.
