Abstract
A pressure relief valve includes a housing and vane that is movable to one of an open position and a closed position. A linear actuator mechanically couples between the movable vane and the housing. The linear actuator is a wire device fabricated from a shape memory alloy. An actuable latching system is configured to retain the movable vane in one of the open position and the closed position for an indeterminate time period.
