Product Introduction: Designed specifically for mobile hydraulic systems, this servo valve from Moog’s D656 series balances performance with the ruggedness required for off-road applications. It features a robust construction to withstand shock, vibration, and temperature extremes, while delivering precise control for mobile equipment. The valve is optimized for compatibility with the hydraulic fluids and system architectures common in mobile machinery.
Technical Specifications: Rated flow is 80 l/min (21.1 gpm) at 35 bar (500 psi) pressure drop. Maximum operating pressure is 300 bar (4350 psi). Operating temperature range is -30°C to 100°C (-22°F to 212°F), suitable for outdoor use in varied climates. The valve is compatible with hydraulic fluids containing anti-wear additives, common in mobile systems. Weight is 4.5 kg (9.9 lbs) for durable mounting on moving equipment.
Functional Features: High resistance to shock (50 g peak) and vibration (20 g RMS) ensures reliability on rough terrain. The spool design minimizes pressure drop, improving fuel efficiency in mobile systems. Optional manual override allows operation during electrical system failures, enhancing safety. Sealed construction prevents contamination from dirt and water, common in off-road environments.
Application Scenarios: Used in agricultural tractors, controlling implement positioning and hydraulic power take-off (PTO) systems for precise farming operations. Integral to forestry equipment, regulating crane and grapple movements for safe log handling. Applied in off-highway trucks, controlling dump bed elevation and steering assistance for improved maneuverability.
