The Tai-Huei Standard (B) Series stands as the most iconic and widely deployed fluid power control component across the global hydraulics industry. Engineered strictly in accordance with international ISO standard mounting dimensions, this series offers seamless interchangeability and universal compatibility with existing industrial configurations.

Building upon a time-tested mechanical foundation, the Standard (B) Series features an optimized internal architecture designed for maximum reliability, cost efficiency, and simplified maintenance. By eliminating redundant complexities, it focuses purely on delivering stable pressure regulation and precise directional fluid control. It is the definitive performance choice for mainstream industrial machinery and hydraulic systems that demand both budgetary efficiency and uncompromising, heavy-duty quality.

Key Applications

• CNC Machine Tools & Metalworking Machinery
• Plastic Injection Molding Machines & Forming Equipment
• Automated Assembly Lines & Conveyor Systems
• Hydraulic Baling Presses & Compaction Equipment
• Hydraulic Power Units (HPUs) & Custom Fluid Power Stations
• Standard General-Purpose Industrial Hydraulic Circuits

The Tai-Huei Low-Temperature and Energy-Saving (Y/YV) Series represents a premium, low-power upgraded solution custom-engineered to meet the rigorous demands of modern smart factories and green manufacturing initiatives. Addressing the critical industry pain points of conventional solenoid valves—namely excessive heat generation and high power consumption during prolonged continuous energization—this series integrates innovative electronic power-saving control technology.

Upon completing the spool shift, the system automatically transitions into a low-current holding mode, fundamentally eliminating coil overheating. This advanced thermal management not only drastically reduces the machinery's overall energy footprint but also effectively prevents the thermal degradation of hydraulic fluid and extends the lifespan of internal seals. The result is a highly reliable, cost-efficient solution for long-term, uninterrupted production lifecycles.

Key Applications

• Continuous-Duty Systems requiring long-term, uninterrupted valve energization.
• Enclosed Control Cabinets and compact, high-density machine enclosures where ventilation is limited.
• Automated Assembly Lines and mass production setups tracking carbon-reduction metrics.
• High-Precision Machining Operations with strict ambient and working temperature constraints to prevent thermal expansion.

The Tai-Huei Shock-Cushioned (S) Series is a specialized line of fluid power solutions engineered as elite shock-absorption experts to eliminate the destructive impact of high-speed, high-pressure hydraulic directional shifts. Utilizing a meticulously engineered damped, cushioned spool architecture, this series smoothly extends the transient spool-shifting window. This ensures a gentle, progressive modulation of the flow passage area, instantaneously mitigating the massive pressure spikes often triggered by rapid directional changes (commonly known as the water hammer effect).

With core advantages focused on eliminating pipeline vibration, reducing mechanical decibel levels, and safeguarding peripheral system components, the S Series effectively prevents costly pressure gauges, transducers, and sensors from experiencing premature fatigue failure. It delivers the ultimate soft-shifting, flexible protection mandatory for modern, close-tolerance machinery.

Key Applications

• High-Precision Grinding Machines requiring flawless surface finishes.
• Hydraulic Press Machines & Heavy-Duty Stamping Equipment subject to severe reversal shocks.
• Precision Machine Tools operating under stringent zero-vibration constraints.
• Hydraulic Robotic Manipulators & High-Speed Material Handling Systems requiring smooth deceleration.
• High-End Industrial Equipment extremely sensitive to hydraulic shock or fluid pressure surges.

Operational Guidelines

• Coil Availability Limitations: Shockless solenoid valves are exclusively available with DC or RF type coils. AC type coils are not provided for this series.
• Component Non-Interchangeability: The armature/solenoid tube of the shockless model is uniquely designed and cannot be interchanged with standard (general) type models.
• Rectifier Connector Requirement: RFN type coils must be paired with the designated RF-specific electrical connector. Failure to use the correct connector will result in a loss of the rectification effect, potentially causing faulty startup or coil burnout.
