Can a boiler water feed / pressure relief valve be repaired?

This valve is the only over-pressure safety in the system. This should only open if there is a blockage in the system (causing a pressure buildup), or if filling the system with a faulty pressure reducing valve. Normally these valves fail due to calcium build up on the interior, which is hard to avoid without having a water softening system installed.
