Detailed content
- Technical Specifications: Referring to the parameters of the D633 series products, the nominal size complies with the ISO 4401 standard (size 03). The maximum working pressure is 31.5 MPa, the flow control range is 3.8 to 100 L/min (1 to 26 gpm), the frequency response is 70 Hz, and the step response is 15 ms. The supply voltage is 24 V DC (18 to 32 V DC), and the rated signal options include ±10 V, ±10 mA, and 4 to 20 mA.
- Functional Features: It is directly driven by a permanent magnet linear motor, which directly drives the spool to move, eliminating the need for pilot oil and reducing energy loss. The spool position is detected by a displacement sensor, and the built-in electronic amplifier performs closed-loop control to ensure high control accuracy. The dynamic response is independent of pressure, with a large driving force and low power consumption.
- Application Scenarios: Suitable for industrial fields that require precise control and high reliability, such as metal forming equipment (shearing machines, bending machines, pipe bending machines), wood presses, injection molding machines, etc., and can be used for electro-hydraulic position, speed, and pressure control of equipment.
