WENZHOU S&G ELECTRICAL MACHINERY CO.,LTD
Founded in 2010, Wenzhou Shengguang Electromechanical operates a 12,000 m² facility in Ruian, Wenzhou, supported by over 100 employees. We focus on the R&D and manufacturing of EGR systems and solenoid valves.
Since 2010, we have focused on deep cultivation within the industry. Marking a milestone in 2020, we expanded our global footprint through numerous auto parts exhibitions and secured National High-Tech and National "SRUN" (Specialized, Refined, Unique, New) certifications. Most recently, in 2025, we were awarded the "Zhejiang Provincial SRUN Enterprise" title, further solidifying our reputation for specialization and innovation.
Product 1
Development technology/material/manufacturing process nameTransmission Solenoid Valve
Innovation Highlights The transmission solenoid valve acts as the "neural switch" for automatic gearboxes, managing hydraulic circuits for precise shifting. Innovations include high-frequency linear proportional control and precision machining, eliminating harshness found in traditional on-off valves. It enables millisecond-level accuracy in flow regulation. Benefits include smoother, quicker shifts with reduced shock and slippage, lower oil temperatures, improved energy efficiency, and extended transmission lifespan.
