Moog G761-3005B Electro-Hydraulic Servo Valve
The Moog G761-3005B is a high-performance two-stage electro-hydraulic servo valve designed for precision flow control in both three-port and four-port configurations. It features a robust design with a dry torque motor and dual-nozzle baffle valve in the pilot stage, paired with a four-way spool valve in the output stage. This valve is engineered for long-term reliability, high dynamic response, and minimal maintenance requirements.
Technical Specifications:
- Flow Rate: 4 L/min to 63 L/min at 7 MPa rated pressure drop.
- Pressure Rating:
- Ports P, X, A, B: ≤ 3,000 psi (210 bar).
- Port T: ≤ 3,000 psi (210 bar).
Detailed content
- Temperature Range:
- Fluid: -40°C to +60°C (-40°F to +140°F).
- Ambient: -40°C to +135°C (-40°F to +275°F).
- Response Time: High dynamic response due to linear torque motor with 250 Hz natural frequency.
- Control Signal: Accepts electrical analog signals for proportional flow/pressure modulation.
- Filtration Requirement: ISO 4406 < 14/11 (conventional use) or < 13/10 (extended lifespan).
- Weight: 7.75 lb (3.52 kg).
Functional Characteristics:
- High Resolution & Low Hysteresis: Ensures precise flow control with minimal deadband.
- Mechanical Feedback: Spool position is feedback-controlled via a cantilever spring rod for stability.
- Dual-Mode Operation: Optimized for four-port configurations, with compatible performance in three-port systems.
- Factory-Calibrated: All settings are pre-adjusted, eliminating the need for user calibration.
- Maintenance-Friendly: Optional fifth port for independent pilot valve control and replaceable butterfly filters.
- Safety Features: Spool returns to neutral position during power loss or cable failure, ensuring load safety.
