A shuttle valveincludes a valve body, a shuttle, and an actuator mechanism. The shuttle valveincludes inlet portsandand outlet port. The shuttlemoves between first and second at rest positions to selectively connect one of the inlet ports to the outlet port and isolate the other inlet port from the outlet port. The actuator mechanismincludes first and second springsandand moves the shuttlefrom one of its positions to another when a set pressure differential is attained between the inlet ports. The actuator mechanismmoves a partial stroke distance to move the shuttlebetween its at rest positions and moves a full stroke distance to additionally open fluid communication between one of the inlet ports and the shuttle
