Abstract
A coupling for a break-away valve assembly includes a coupling and an adapter, the coupling including: a valve arranged in an annular body, the annular body having a valve seat including a first portion and a second portion, adjacent to the first portion, of greater internal diameter relative to the first portion, the valve being biased in a first direction to seal against the valve seat on disconnection of the coupling from the adapter, wherein the valve is biased in a second direction, and the valve is adapted to extend past the first portion into the second portion of the valve seat to release a volume of fluid if the pressure acting on the valve exceeds a predetermined surge pressure threshold.
