Product Introduction: The D636-262-0001 is a direct-acting servo valve (DDV) with closed-loop spool position control, eliminating the need for a pilot stage. It is designed for high-precision flow control in electro-hydraulic systems, offering fast response and energy efficiency. Its compact design makes it suitable for integration into space-constrained equipment.
Technical Specifications: The maximum operating pressure is 350 bar (5,000 psi). The rated flow is 3.8 to 100 l/min (1 to 26.4 gpm) at 70 bar (1,000 psi) pressure drop. The step response time is ≤20 ms, with a frequency response of 40 to 60 Hz. It operates on 24 VDC and accepts ±10 V or 4-20 mA signals. The valve weighs 6.3 kg and features ISO 4401 mounting.
Functional Features: Direct drive by a permanent magnet linear force motor eliminates pilot oil requirements, reducing energy loss and improving efficiency. Closed-loop control via an integrated sensor ensures high precision (hysteresis <0.2%, resolution <0.1%). It includes a spring-centered fail-safe mechanism, returning the spool to neutral during power loss. The valve’s design resists contamination, extending service life.
Application Scenarios: Ideal for CNC machine tools, controlling axis movements for high-precision machining. In wind turbines, it adjusts blade pitch to optimize energy capture. It also regulates hydraulic pressure in medical imaging equipment, ensuring stable operation of precision mechanisms.
