Abstract
A number of improved excess flow valves are disclosed wherein pressure drop is optimized through the device to maximize efficiency while minimizing shut-off flow rates. Flow restrictions are minimized throughout the valve structure and maximized across a valve closure plate, eliminating flow restriction variations caused by orientation of the valve components. A magnet having radially opposing poles optimizes the magnet's attractive force relationship with the valve plate.
