Methods and apparatus are provided for retaining a hinge shaft of a check valve with a bushing. The check valve includes a valve body defining a flow passage therethrough; a hinge shaft; a bushing coupled to the valve body and welded to the hinge shaft; and a closure element pivotally mounted on the hinge shaft for opening and closing the flow passage.

Check valves with hinge shafts retained by welding

An air turbine starter valve able to open despite being frozen shut. Dual actuators apply sufficient torque upon an air turbine starter valve to overcome obstructions presented by frozen moisture. By applying separate and generally-aligned torques, the actuators are able to provide sufficient force to overcome the adhesion provided by frozen moisture between the valve plate and adjacent structures.
