Product Introduction: It belongs to the Moog D660 series servo proportional valves and is a pilot-operated proportional valve for analog signals. The valve can be configured as a two-stage or three-stage valve according to the dynamic performance requirements of the application. It has the characteristics of high rated flow, excellent dynamic response, and reliable operation, and can be applied to various electro-hydraulic control systems to achieve precise control of flow, position, speed, pressure, or force.
Hydraulic Parameters: The rated flow rate is 30-1500 l/min (8-395 gpm) per unit at a pressure difference of 5 bar (75 psi); the maximum flow rate of the Size 10 specification can reach 3600 l/min (950 gpm); the maximum operating pressure is 350 bar (5000 psi); the step response time is 10-50 ms at 210 bar (3000 psi).
Electrical Parameters: The supply voltage is 24 VDC (18-32 VDC); the rated signal options include ±10 V, ±10 mA, and 4-20 mA.
Installation Standard: Complies with ISO 4401 Size 05-10 (D661, D662, D663, D664, D665 correspond to different sizes).
Functional Features:
It can be used as a two-stage or three-stage valve, and the configuration is flexible according to the required dynamic performance.
Optional ServoJet or nozzle flapper pilot valves to meet different control precision requirements.
The improved pilot stage design significantly improves dynamic response performance.
The product has a compact structure, is easy to install, and occupies a small space in the system.
Made of corrosion-resistant materials and with a durable structure, it can withstand harsh industrial environments.
Application Scenarios: Suitable for industrial machinery, such as hydraulic control systems of machine tools and presses; automation systems, including automated production lines and robotic hydraulic control; hydraulic power units, used to regulate the output flow and pressure of the power unit; also applicable to aerospace, steel mills, plastic machinery, and test systems that require precise control of hydraulic motion.
