Product Introduction: This model is part of Moog’s D662 series, a pilot-operated proportional valve designed for analog signal control. It serves as a key component in electro-hydraulic systems, converting electrical signals into modulated hydraulic flow to control actuator speed, position, and force. The valve’s modular design allows customization for specific flow and pressure requirements, making it versatile across industries.
Technical Specifications: The maximum operating pressure is 350 bar (5,000 psi). The rated flow ranges from 30 to 1,500 l/min (8 to 395 gpm) at a 5 bar (75 psi) pressure drop per land. The 100% step response time is 10 to 50 ms at 210 bar (3,000 psi). It operates on 24 VDC (18 to 32 VDC) and accepts ±10 V, ±10 mA, or 4-20 mA signals. Mounting conforms to ISO 4401 sizes 05 to 10.
Functional Features: The valve’s optimized pilot stage enhances dynamic response, while optional ServoJet or nozzle-flapper designs accommodate varying performance needs. It offers multiple fail-safe options to protect equipment during power loss. The large internal flow passages maximize flow capacity, suitable for high-demand applications. Integrated electronics simplify system integration and ensure consistent performance.
Application Scenarios: Used in plastic extrusion lines to control screw speed and die pressure, ensuring uniform product dimensions. In marine systems, it regulates thruster and steering actuators for precise vessel maneuvering. It also controls hydraulic presses in automotive manufacturing, applying consistent force during component assembly.
