At its core, the EH Series eliminates the need for separate hydraulic power units (HPUs) and complex piping by integrating a high-pressure cylinder, precision feedback sensors (e.g., position encoders for real-time position monitoring), and a compact valve manifold directly into the unit. This all-in-one design reduces installation time, minimizes space requirements, and lowers maintenance costs—critical for applications where space is constrained (e.g., agricultural machinery, construction equipment, or industrial automation lines). The series also supports seamless compatibility with PVED-CLS controllers, enabling advanced control features like proportional speed adjustment, position locking, and overload protection.

• Pressure & Flow Capability: Engineered to handle a nominal system pressure of 210 bar (with peak pressure options up to 280 bar for short-duration loads) and a return oil pressure (T-port) of ≤25 bar. Flow rates are configurable across 12, 20, 30, 40, 50, or 70 l/min, allowing customization to match specific application speed and force requirements.
• Mechanical Strength: Axial load capacity reaches up to 160 kN (varies by model), with spindle options including trapezoidal-thread spindles (ideal for intermittent-duty cycles) and ball-screw spindles (optimized for high-duty cycles and smooth, low-friction operation). Stroke lengths are flexible, ranging from standard 500 mm to custom lengths, accommodating linear motion needs from small adjustments to large-scale actuation.
• Speed & Precision: Offers a maximum operating speed of 0.24 m/s and a minimum speed of 0.18 m/s, with position accuracy within ±0.1 mm when paired with compatible feedback systems—critical for applications like material handling, press automation, or precision lifting.

Built to withstand harsh industrial and outdoor conditions, the EH Series features an IP66 protection rating, ensuring dust tightness and resistance to high-pressure water jets. Its operating temperature range of -40°C to +70°C allows reliable performance in extreme cold (e.g., construction in winter climates) or high-heat environments (e.g., foundries or outdoor mobile equipment). Additionally, the series meets SIL2 safety standards (per IEC 61508) when used with controllers, providing fail-safe operation for applications where safety is paramount (e.g., heavy load lifting or machine guarding).

The EH Series operates on a 9–32 VDC supply voltage, making it suitable for both 12V and 24V mobile systems, with low power consumption (7W for single solenoid PVE-type valves) to minimize energy draw. Hydraulic interfaces (P, T, L, R ports) use M18×1.5 (3/4–16 UNF) threads, while the load-sensing (LS) port uses M12×1.5 (7/16–20 UNF) threads—standardized fittings that simplify integration with existing hydraulic systems. Installation options include flange-mounted or in-line configurations, further enhancing adaptability to diverse machine designs.

From agricultural machinery (e.g., tractor implement control, harvester adjustments) and construction equipment (e.g., excavator arm actuation, crane positioning) to industrial automation (e.g., assembly line robotics, press machines) and renewable energy (e.g., wind turbine pitch control), the EH Series delivers consistent performance across sectors requiring precise, heavy-duty linear motion. Its ability to balance power, precision, and durability makes it a preferred choice for engineers seeking to optimize machine efficiency and reduce total cost of ownership.
