Ltd. is located in Lishui, Zhejiang Province, in response to the provincial government "to help mountainous areas in 2022 Liandu District Market Supervision Bureau and Industrial Park Investment Promotion Bureau to lead the landing, the county high-quality leapfrog development" call, Liandu District Market Supervision Bureau decided to build a valve testing laboratory, to create a national valve plus test Centre, together to promote the quality of the valve industry in Lishui City. Therefore, Lishui valve inspection came into being. Based on the valve industry testing, the service object extends to bearings, steel pipe fittings and casting and forging and all other metal materials, pressurised equipment related to the pillar industries, to enhance the convenience and economy of testing.

Lishui Valve Inspection has been basically capable of testing in the areas of sulphur and hydrogen resistance, flow resistance, API622, API624, ISO15848, TA-Luft and other fugitive and high and low temperature testing. We have reached a preliminary agreement with China University of Weights and Measures, the establishment of measurement of scientific and technological achievements of the University of transfer centre, and Zhejiang University has also reached a preliminary intention to establish the Zhejiang University Lishui Research Institute.

Company business scope
