(Taiwan, Taichung) August 12th, 2026.

YUATSUSEIKI HYDRAULIC, a premier production line under YOULI Hydraulic Industrial Co., Ltd. with a rich history in manufacturing high-precision fluid power solutions since 1975, is pleased to announce the onboarding of its digital product catalogue onto Automation Studio™. This multi-brand digital integration will deliver certified simulation-ready components to fluid power designers worldwide. 

This partnership with Famic Technologies will provide users access to exact digital replicas of YUATSUSEIKI’s long-standing control valve lines, enabling virtual testing and validation under real-world conditions before physical sourcing. This release comes after the corporate group has rolled out the complete product catalogue of YOULI Hydraulic in Automation Studio™, including its prominent lines of proportional directional control valves.

Comprehensive Control Valve Portfolio for Advanced System Design
This catalogue deployment encompasses YUATSUSEIKI's extensive range of industrial fluid power solutions, featuring:

• Pressure Control Valves (Relief Valves, Reducing Valves, Back Pressure Valves),
• Flow Control Valves (Throttle Valves, Check Valves),
• Directional Control Valves (Solenoid-operated Directional Control Valves and Manual Valves),
• Pre-Fill Valves (Engineered for surge-free decompression control).

Every component model incorporates precise fluid dynamics properties, such as viscosity variations and pressure drops, allowing engineers to minimize performance discrepancies and accelerate machine time-to-market.

YUATSUSEIKI’s Solenoid-operated Directional Control Valve
YUATSUSEIKI’s solenoid-operated directional control valves are designed for low internal leakage, providing reliable directional control and stable performance in hydraulic systems. The product range includes the DSHG Series in sizes 03, 04, 06, and 10, as well as the 4YWE Series in sizes 06 and 10, offering versatile solutions for a wide range of industrial hydraulic applications. The 4YWE6/10 Series adopts a standard direct-acting solenoid as its core actuation mechanism, delivering fast, direct, and reliable switching for precise hydraulic flow control. The valves are available with either a wet-type DC solenoid, offering excellent heat dissipation and sealing for DC power applications, or a removable-coil AC solenoid, which enables convenient installation, removal, and replacement of the coil for easier maintenance in AC applications. 
The solenoid assembly can be rotated through 90°, providing greater flexibility for installation according to available space and piping orientation. In addition, the removable-coil design allows coil replacement without draining the hydraulic oil, helping simplify maintenance procedures and reduce equipment downtime. Combined with their low-leakage performance, reliable direct-acting operation, flexible AC/DC solenoid options, and robust construction, the YUATSUSEIKI 4YWE6/10 Series provides a dependable solution for directional control in demanding industrial hydraulic systems.
