Taihuei Hydraulic — TAI-HUEI
Half a Century of Craftsmanship, Defining a New Standard in Fluid Power
Since 1975, we have specialized in the precision research and development of high-pressure, ultra-quiet hydraulic directional valves and critical fluid components. With Taiwan-made, highly vertically integrated machining technology, we deliver the most reliable core-drive solutions for high-end industry and smart machinery worldwide.
ABOUT TAI-HUEI
Committed to Quality | Customer First
Taihuei Hydraulic Industrial Co., Ltd. is a professional manufacturer of solenoid directional valves and hydraulic components. Since its founding in 1975, Taihuei began as a pneumatic and hydraulic distributor, and through keen insight into market needs and deep practical experience, transitioned to technical cooperation with Japanese manufacturers and production in Taiwan. By building our own brand, we are dedicated to providing efficient, precise hydraulic drive solutions for customers worldwide.
With over 50 years of industry experience and the R&D expertise behind our W series, we successfully developed the innovative LW and DL solenoid valves, significantly reducing system noise and enhancing operating pressure resistance. We subsequently developed multiple wiring configurations such as the DT, 2W, and M4 types to meet diverse market demands, becoming an indispensable technology partner for customers in precision machining and automated production.

FOUND
Laying the Foundation as a Hydraulics Leader
Starting as a pneumatic and hydraulic distributor, we partnered closely with major Japanese manufacturers to launch high-precision assembly and production in Taiwan, beginning our path toward independent R&D and highly self-sufficient machining.
1999
CE CERT
Taiwan's First CE Safety Certification
Honored as Taiwan's first solenoid valve manufacturer to pass EU CE certification, with our safety and pressure-resistance quality earning strong recognition in global markets.
PRODUCTS TECHNOLOGY
Core Products & Manufacturing Innovation
After half a century of refining our W-series technology, we usher in a new era of LW, DL, and multifunctional quick-connect systems.
DL / LW SERIES
Full High-Flow, High-Pressure
LW & DL Low-Noise, High-Pressure Solenoid Valves
Building on the high-flow development experience of the classic W series, our R&D team reshaped the internal flow-path geometry to greatly eliminate the oil-hammer effect during directional switching. The streamlined, precision-cast housing offers outstanding shock and high-pressure resistance.
- Precision-cast valve body with tensile-resistant, anti-vibration structure; max pressure up to 31.5 MPa
- Optimized flow-path geometry minimizes oil resistance and system operating noise
- Flexibly compatible with various DC and AC valve cores
The result of in-depth evolution from the original W series
Major flow-path geometry upgrade
DT / 2W / M4 SERIES
Smart Quick-Connect Connectors
Multi-Wiring Solenoid Valves for Smart Automation
Built for Industry 4.0 smart PLC control cabinets, perfectly integrating multifunctional terminal configurations with high-spec protection to reduce complex on-site wiring procedures and improve reliability under extreme operating conditions.
- Offers diverse quick-connect ports including German-style DT, 2W dual-coil control, and M4
- IP67 top-grade waterproof and dustproof structure, resistant to chemical cutting oils and high temperatures
- Quick-connect design cuts factory control-cabinet wiring and maintenance/installation time by 60%
Seamless integration with modern smart production and PLC communication
Smart quick-connect system
