A surface controlled flow control valve (“SCFCV”) used in a wellbore is protected from potentially damaging substances by adding a temporary plug that blocks communication between the substances and the valve. Potentially damaging substances include corrosive fluids, fluids with entrained particles, cement, or other substances that harden over time. The types of SCFCV valves include gas lift valves and inflow control valves. The plug is made from a material that is initially cohesive and blocks the substance from contacting the valve. But after a designated period of time, the material degrades and is no longer sufficiently cohesive to act as a barrier and shield the valve from the substance. Before the designated time expires, wellbore procedures involving flowing the substance in the wellbore are completed, and the wellbore is flushed before the valve operation resumes.
