Abstract
A fuse pin valve includes a housing, a piston, and a mechanical fuse, such as a fuse pin. As assembled, the piston is movably disposed in the housing and is retained in a static position by the fuse pin. Upon a certain pressure (e.g., an abnormal pressure) acting on the piston, the fuse pin fails, thereby releasing the piston to move from a first or start position to second or end position. In the start position of the piston, the valve is in a first operational state (e.g., a closed state). In the end position of the piston, the valve is in a second operational state (e.g., an open state, fully open states, etc.). In other embodiments, in the start position of the piston the valve is in an open state, and in the end position of the piston the valve is in a closed state.
