Product Introduction: Part of Moog’s renowned G761 series, this servo valve is engineered for precise flow control in hydraulic systems. It builds on decades of Moog’s expertise in servo valve technology, featuring a robust two-stage design with a double-nozzle pilot stage and mechanical feedback. The valve converts electrical signals into precise hydraulic flow, making it a critical component in high-performance control systems requiring accurate positioning, speed, or force regulation.
Technical Specifications: Rated flow ranges from 4 to 63 l/min (1 to 16.6 gpm) at a pressure drop of 35 bar (500 psi). Maximum operating pressure reaches 350 bar (5000 psi). The pilot stage uses a dry torque motor with symmetrical nozzles, while the output stage employs a closed-center four-way sliding spool. Spool position is maintained via a carbide-tipped feedback wire for long-term accuracy. Operating temperature ranges from -20°C to 70°C (-4°F to 158°F).
Functional Features: Delivers high dynamic response with a frequency response of up to 150 Hz, ensuring rapid adjustment to input signals. Low hysteresis (<0.5% of full scale) and high resolution enable precise control. The rugged construction resists contamination and vibration, ensuring reliability in harsh industrial environments. Compatible with both three-way and four-way hydraulic circuit configurations, enhancing versatility.
Application Scenarios: Widely used in industrial machinery such as injection molding machines, where it controls mold clamping force and injection speed to improve part quality. Integral to metal forming equipment, including presses and rolling mills, for regulating material feed rates and forming pressure. Also employed in test benches for simulating dynamic loads, ensuring accurate replication of real-world operating conditions.
