A shut off safety valve for flow control of fluid liquids and gases through a conduit transport path responsive to flow rates exceeding predetermined limits, comprising, a plate valve member eccentrically mounted off center in said conduit path to establish by fluid flow therepast a stable position

A shut off safety valve for flow control of fluid liquids and gases through a conduit transport path responsive to flow rates exceeding predetermined limits, comprising, a plate valve member eccentrically mounted off center in said conduit path to establish by fluid flow therepast a stable position not substantially impeding fluid flow and engaging the conduit only by means of pivot members to pivot from an open position parallel to fluid flow through the conduit to a closed position substantially reducing the flow of fluid and presenting airplane wing type surface structure with a substantially flat surface on one side and curved surface on the other side responsive to fluid flow at a flow rate above a predetermined threshold past both said surfaces for providing a lift to pivot the valve member in response to the fluid flow from the open position toward the closed position where it is aided in closure and kept closed by fluid pressure in the conduit as a function of the off center eccentric mount.
