Shanghai Jinhai Hydraulic Co., Ltd. was founded in 1995. In the early days, it introduced German technology and gathered various talents in China who were involved in the production of REXROTH series valves. The company has strong technical strength. Its research and development products include three major categories of hydraulic valves: pressure, flow, and direction. The products are excellent and widely used in fields such as engineering machinery, aviation, and railways, and have received unanimous recognition from users. After establishing the factory, in addition to producing the Powerseal series valves, we adhere to the corporate spirit of unity, hard work, practicality, and innovation. We have developed, introduced, and produced the Oil Research series products, which have stable product quality and are widely welcomed. In addition, we also undertake the design and manufacturing of various non-standard hydraulic systems and stations. The DBD6 series valve produced by Shanghai Jinhai Hydraulic Co., Ltd. has been used in railways for more than 20 years, accumulating rich experience. The 4WE, DSG, WEH, DSHG reversing valve, DB series pressure valve, Z2FS, Z2S and other stacking valves are widely used in various hydraulic systems such as environmental protection equipment, engineering machinery, forging machinery, machine tools, etc. We always adhere to the principle that the requirements of our users are our ultimate goal. We also promise to manufacture, inspect, clean, assemble, and test our products under the ISO9001 quality assurance system, strictly following national standards, departmental standards, and mandatory standards. All products leaving the factory undergo 100% testing to ensure quality and reliability.
