摘要：
A device for actuating a pneumatically operated gas-line shut-off valve is disclosed. The device comprises a shape memory alloy wire that is actuated by the application of electrical current. When the shape memory alloy wire is actuated, it opens a spring loaded air exhaust valve that releases the pneumatic pressure holding the gas-line shut-off valve in the open position. The shape memory alloy wire can be activated with an electronic remote control device or through direct wiring thereto.
