after doing all the priliminary inspection if u found the
valve is struck, u can directly give the air supply to the
actuator not:direct applying og air supply may diamage the
valve it should be done with sufficiant care.if the struck
is minor by repeaded giving of supply air will slowly
remove the struck.agfer this still its struck u can remove
the valve from the praocess line and chel the valve body
whether any solid material bloks the way.if that u can
clean and fix it back
