Any ways of preserving idle pneumatic valves prevent damage of rust

no survivor and aqueous solution, pneumatic valve chamber should be purging is clean. Pneumatic valve outside should be wiped clean, no dirt, grease, dust.
any ways of preserving idle air valve to prevent rust damage:
a, regular care:
should be checked regularly, idle time longer pneumatic valves. Regular care, pneumatic valve to prevent corrosion and damage. Idle time is too long for pneumatic valves, shall be carried out together with equipment, devices and pipeline pressure test after passing before use.
2, protective maintenance:
human chatter and disassembly, prevent bricks and impact. When necessary, to deal with pneumatic valves for fixed activity area, for packaging of pneumatic valve maintenance.
3, anticorrosive processing:
pneumatic valve sealing surface, pneumatic valve stem, stem nut, machining parts such as appearance, pulled out of the stuffing box packing, prevent galvanic corrosion of the pneumatic valve rod. Rust inhibitor according to specific situation, grease, paint parts should besmear brushs antirust paint.
4 pieces, or pneumatic valve:
can't split open a moving west, pneumatic valve after missing parts. Should complete pneumatic valve parts, for the next step is to use the invention in good condition, ensure the pneumatic valve is in good condition.
5, clean up the pneumatic valve:
