Fully hydraulic steering system

Cycloidal Rotary Valve Fully Hydraulic Steering System | Lightweight, Precise, Safe, Reliable, and Widely Adaptable

Product Overview: This fully hydraulic steering system is a cycloidal rotary valve type, open-heart non-responsive, designed specifically for off-road mobile machinery and heavy vehicles. Eliminating mechanical linkages, it transmits steering power solely through hydraulic pressure, achieving light-force operation, precise follow-up, and stable reliability. Suitable for construction machinery, agricultural machinery, forklifts, special vehicles, and ship steering, it is the ideal steering core for heavy-duty, low-speed equipment.

Core Advantages

Easy and effortless operation: High hydraulic power assist, low steering wheel torque, reducing fatigue during extended operation.

Precise and responsive steering: Sensitive valve distribution ensures precise synchronization between steering wheel angle and wheel deflection, with no lag.

Safe emergency steering: Manual emergency steering is available in case of engine stall or hydraulic failure, ensuring driving safety.

No mechanical linkages: Flexible installation and layout, simplifying the main unit structure and reducing failure rate and maintenance costs.

High-pressure sealing and leak-proof: Multi-stage sealing and precision fit ensure high pressure resistance, back pressure resistance, and long-term leak prevention.

Durable, vibration-resistant, and long service life: Precision cycloidal pair and high-strength housing provide impact and vibration resistance, ensuring stability under harsh operating conditions.

High versatility and easy replacement: Compliant with industry standard interfaces, supporting multiple displacements/flanges/ Optional oil port for easy replacement

Performance Features: Smooth forward and reverse rotation, shock-free, low noise, and stable operation

Adaptable to a wide flow and pressure range, compatible with various hydraulic systems
