About Hoyea

Hoyea, established in 1993, as the leader in the field of fluid power transmission & control in China, has devoted itself to the development of electro-hydraulic control technology.


With strong technology basis and the advantage of hydromechanics, Hoyea develops innovative ability, and at present has large quantities of independent technology, which fill the domestic blank market a lot. Multiple advanced patents, such as “differential pressure proportional pressure flow composite valve”, and “bidirectional different pressing feedback type of proportional pilot-operated slide valve” shape a high-quality technical supporting system of HOYEA. The company won the title of “National High Technological Enterprise”, “Zhejiang Patent Demonstrating Firm”, “Zhejiang Excellent Technology Innovation Enterprise”. Various kinds of products win the 2nd and 3rd place of “Science and Technology Progress Prize of Zhejiang Province”, and “Outstanding New Products Prize” awarded by the national industrial organization. Among them, the proportional pressing flow comples valve is classified as the national key new product, national-level Torch program project, whereas the proportional hydraulic component of new electro-hydraulic valve and the other two products has won the innovative fund project of National Science and Technology Department for technology-based small-and-medium-size enterprises, moreover, the proportional hydraulic component of new electro-hydraulic valve has also win the “National Major Achievements Transformation Projects” issued by the National Industrial Information Department.


The company has passed through ISO9001 quality system authentication, CE certificate, explosion proof safety certificate and typical certificate of mineral products safety. The company has advanced processing equipment and hardware facilities. The products cover the whole fields of hydraulic components, and have already been widely applied in each field. There are routine hydraulic pressure valves, proportional valves, cartridge valves, restrictive valves, explosion isolation valves and proportional solenoid, internal gear pump and pneumatic components.


Therefore, Hoyea can offer its customers with comprehensive and advanced electro-hydraulic solutions, high cost-effective products, help them face high market competition, initiate its competitive ability, and create more value for the customers.




    Yinzhou Sida Hydraulic Parts Factory was established in 1993, and started the professional research and manufacturing of hydraulic components and system.


    "Ningbo Hoyea Machinery Manufacture Co.,Ltd" was created in 1995 with 1.2 million RMB.


    In 1996, the company was invested to build the workshop of solenoid, have the capacity to produce anti-explosion, direct-operated proportional solenoid.


    In 1997, the development strategy of "on the basis of hydraulic components, and on the direction of complete appliance" was determined, and the production line of rubber machine was invested, in order to build up a production chain of complete appliance.


    In 1998, the first transfer type molding machine for rubber was successfully designed and developed, which filled the gap of domestic rubber machinery industry.


    In 2000, the segment factory was built in Shiqi Town, Yinzhou District.


    In 2001, by the cooperation with Zhejiang University, the National Electric Fluid Control Technology Research Center Ningbo Branch was created in Hoyea.


    In 2002, Lu Yongxiang, the Chinese Agricultural Technician, who is also the university tutor of Chairman Zhentao Weng visited Hoyea for the first time.


    In 2003, 20 million RMB were invested to establish the first-stage of construction of "Ningbo Hoyea Machinery Manufacture Co.,Ltd" in Hengxi Town, Yinzhou District, and the company began stepping into a comprehensive expansion stage.


    In 2004, the company has made a strategic restructuring, "Ningbo Chap Mechan-Electro-Hydraulic S&T Development Co.,Ltd" was established as the Holdings Corporation, which owned three subsidiaries, "Ningbo Hoyea Machinery Manufacture Co.,Ltd", "Ningbo Chap Machinery Manufacture Co.,Ltd", and "Ningbo Hopea Industrial Control Technology Co., Ltd". They operated three big business, in terms of hydraulic,complete appliance, and electric fluid control technology.


    In 2008, Hengxi Factory, which locates off the Shore of Dongqian Lake, finished the second-stage of the project, and it covered an area of 60000m2, that was building area of 50000 m2. After then, the subsidiaries, "Ningbo Chap Machinery Manufacture Co.,Ltd" and "Ningbo Hopea Industrial Control Technology Co., Ltd" moved into this factory, and combined with Ningbo Hoyea, several enterprise pooled into a holding company, which covers the first place of high-tech enterprises in Hengxi within the electromechanical fluid industrial chain, and formed an electromechanical fluid trinity strong momentum of development.
