Established in 1997, Shingwang specializes in the manufacture of various auto change-over valves. We developed an LPG-electronic type auto-change over valve for the first time in Korea and obtained two patents for it. We also developed high-pressure gas (oxygen, nitrogen, argon) auto change-over valves in 2003 and cryogen liquid gas type auto change-over valve in 2004. Our products are excellent for prevention of any kinds of risk caused by exhaustion of gas so are essential for all facilities using gases and needing regular gas supply.We can manufacture 1,000 pieces per month. We are happy to accommodate your requests regarding any of our products.
