The researching marine super high pressure air drying and filtering technology

Development of PN40 DN32 pilot operated high pressure air electromagnetic valve;

Whereas, this paper discusses two methods, the first way is that to blow away the rubbish using the high pressure gas, the second is to dig out the sludge with the automatic grab.

Since high-pressure air has dangers of explosion and operational aspects , it should follow some basic requirements for safety operation when management and operation of high-pressure airgun system are carried out, which avoids the injury of personnel.
