On October 28, 2026, Hangzhou Dongchen Intelligent Technology signed a strategic-level cooperation with UK-based Rotork at Dongchen’s smart-manufacturing base: Dongchen chairman Luo Linhua and Rotork APAC VP & China GM Xiang Lei signed for both sides. One side brings national "little giant" extreme-duty manufacturing capability, the other nearly 70 years of global high-end actuator technology — against the backdrop of ABB’s announced acquisition of Rotork, a Chinese company binding itself deeply to Rotork technology is worth the industry’s attention.
Rotork: founded 1957, headquartered in Bath, UK; LSE-listed; operations in 170+ countries; full actuator portfolio (electric/pneumatic/hydraulic plus smart control accessories); hundreds of thousands of units in service worldwide; Chinese production entity Rotork Fluid Technology (Suzhou) established 2023 with a US$60M investment.
Dongchen Intelligent: national-level "little giant" and high-tech enterprise, two decades in high-end fluid-control equipment; operating envelope −196 °C to 650 °C, up to PN76 MPa, control accuracy ±0.5%; references include a 1,030 MW ultra-supercritical unit; led the Zhejiang-manufacturing standard for desuperheating-reducing units; customers span CNNC, CHN Energy, major oil-services and the big-five power groups.

| Product fit | High-end intelligent fluid-control solutions for global energy and fine-chemical project standards |
| Service | Rotork global network + Dongchen local manufacturing service: integrated worldwide technical support, spares, quality traceability, long-term O&M |
| Market | "High-end hardware + international smart drive + standardised global service" for major projects at home and abroad |
Technical exchange between the two parties (source: valve trade press)
Two points stand out. (1) Timing: during the handover period of ABB’s Rotork acquisition, Rotork chose to bind deeply with a Chinese extreme-duty valve maker — an endorsement of both the Chinese high-end market and Dongchen’s manufacturing, adding a new localisation path for Rotork in China. (2) Division of labour: Dongchen contributes extreme-duty bodies and precision conditioning; Rotork contributes smart drives, monitoring and global service — complementary rather than competing. This "body manufacturing × smart drive" template may become a new route for Chinese high-end valve exports.
