Product Introduction: It is a pilot-operated servo valve of Moog’s D661 series, which adopts an optimized valve body design and an improved servo jet pilot valve design. It has excellent dynamic response and control performance, and is suitable for various industrial control systems requiring high precision and high dynamic response.
Technical Specifications: It conforms to ISO 4401 size 05. The rated flow is 20 to 200 l/min (5.3 to 53 gpm) at Δp 35 bar (500 psi) per land, and the maximum flow can reach 250 l/min (65 gpm) when the second T-port is connected. The maximum operating pressure is 350 bar (5,000 psi), the 100% step response time is 6.5 to 14 ms at 210 bar (3,000 psi), the supply voltage is 24 VDC (18 to 32 VDC), and the rated signal options include ±10 V, ±10 mA, 4 – 20 mA.
Functional Features: It has high control precision, which can accurately control the flow and pressure of the hydraulic system according to the input electrical signal. The dynamic response speed is fast, which can quickly adjust the valve core position to respond to the change of the control signal, ensuring the stability and rapidity of the system. It also has strong anti-pollution ability, which can work stably in harsh hydraulic oil environments. In addition, it has different fail-safe options to choose from, which can be matched according to the specific requirements of the application to ensure the safe operation of the system.
Application Scenarios: It is applied to the aerospace field to control the hydraulic system of aircraft, such as the control of the aircraft’s flight control system and landing gear, to ensure the safe flight and landing of aircraft. It is also used in the automotive manufacturing industry, such as the control of the hydraulic system of the automobile body welding line and the painting line, to improve the production efficiency and quality of automobiles. In addition, it can be used in the hydraulic control system of power generation equipment, such as the control of the turbine’s speed and load, improving the efficiency and stability of power generation.
