On July 12, 2005, Hefei General Machinery Certification Center conducted a site audit on the general machinery product certification (GC certification) of valve products applied by Jiangsu Suyan Valve Machinery Co., Ltd. The audit team conducted a serious review of the business, and carried out the product sample. At present, the company has successfully passed the site audit and product testing. As the law requires that the valve products must obtain the manufacturing license of special equipment, the company will issue the GC certification certificate and the GC certification mark for the product after obtaining the manufacturing license of the valve product special equipment.
