The seven series on this site cover process, steam, cryogenic, and corrosive service:
Each valve is sized and built to order from the operating data of its tag.
Production and testing cover CNC machining, 15 pressure test benches and a full-function test bench rated to 10 MPa. The plant also runs cryogenic tests down to -196 °C and clean nitrogen tests on degreased valves. Raw materials are checked by magnetic particle, spectrum, X-ray, chemical, tensile, and spring tension tests.
Not every material or test comes from inside our own plant. With our partners and suppliers we run a supply and quality platform. Special materials, raw material checks, and tests outside the range of our own benches come from qualified suppliers and third-party laboratories.
The Quality and certifications page lists the certificates, type tests, and patents, with their numbers and dates.
Luofu pressure relief valves are in service with these end users:
One project on record: 476 pressure relief valves for the Zhongke (Guangdong) refining and petrochemical integration project, supplied through the EPC, Sinopec Luoyang Engineering.
