This is application for cryogenic industry. We participated many important LNG terminal projects in past 10 years which design temperature would reach -196 ℃.  Especially for liquid hydrogen and liquid helium service condition，the valve operation temperature would reach below -250 ℃.

For refining and petrochemical application, we also participated many important projects in china. The maximum size up to 20in. The material is covering Carbon Steel, Alloy Steel, Stainless Steel, Duplex-SS, Ni-Alloys, etc.

We have a rich performance in the air separation industry and strive to become a first-class safety valve manufacturer. we cooperated with the foremost companies in globe over past 10 years, especially Linde and air liquid. We provide a large number of cryogenic relief valves on their projects every year.

Our safety valves are widely used in the whole coal chemical industry, such as coal to olefin, coal to liquid, coal to gas.  The working condition is very harsh and the medium is containing the corrosive and coal impurities. So such service condition shall need high performance valves.

Our safety valve factory already offered almost kinds of high-quality safety valves for fine chemical industry. The pressure rating range is from class 150 to class 2500, the size is from 2in to 20in. The valve range is covering safety relief valve, tanker breathe valve and change over valve.

Our company is specialized in the design and manufacture of safety valves in the steam turbine industry. We cooperated with the foremost turbine companies in china. Our products assembled with their turbine equipment, and together offered to the client.
