Claim 13:
14. A protection process for a fluid flow line comprising:
(i) provision of a protection device according to claim 1 on a fluid flow line, the valve being in the open position to let the fluid flow through the flow line;
the fluid flowing in the flow line being sampled from the flow line and flowing to the rupture element through the fluid sampling passage;
(ii) when the pressure of the fluid sampled from the flow line is above the predetermined threshold pressure, rupture of the rupture element with the fluid sampled from the flow line in the fluid sampling passage to open the rupture element;
(iii) application of the fluid sampled from the fluid flow line on the fluid actuated surface through the open rupture element,
the fluid sampled from the fluid flow moving the fluid actuated surface to pass the valve from the open position to the closed position against a biasing force of the biaser.
