Frequently Asked Questions
1. What is the main function of this valve?
This is a direct-operated proportional relief valve. Its primary function is to continuously and precisely regulate hydraulic system pressure by receiving electrical control signals (typically 0-20mA or 0-10V), while also serving as a safety valve to prevent system overpressure. It's designed for remote electrical control of pressure in hydraulic systems.
2. What does the "80" in the model code indicate?
The "80" specifies the maximum pressure setting capability of 80 bar. This is a mid-range pressure setting in the DBETR series. The valve can be electrically adjusted to regulate pressure from 0 to 80 bar, making it suitable for a wide range of industrial applications.
3. What are the key electrical specifications?
- Operating voltage: 24V DC (±10%)
- Nominal current: Typically 0.8-1.0 A (varies by coil type)
- Coil resistance: Approximately 19-29 Ω (at 20°C)
- Electrical connection: DIN 43650 standard plug connector (K4 type)
- Requires compatible proportional amplifier
- Control signal: 0-10V or 4-20mA
4. What does the "K4" suffix indicate?
The "K4" indicates the electrical connection type. Specifically, it means the valve comes with a DIN 43650 standard plug connector (without mating connector) for the proportional solenoid. The "K" series typically refers to the connector configuration, with "K4" being a specific variant in this product family.
5. How does this 80 bar model differ from the 30 bar version (DBETR-1X/30G24K4M)?
The key difference is the pressure setting range: this model has a 0-80 bar range, while the 30 bar version is limited to 0-30 bar. All other core parameters (size, voltage, current, port size, connector type) remain identical. The 80 bar version provides higher pressure capability for applications requiring medium-pressure control.
6. What are the installation and maintenance considerations?
- Port size: NG6 (ISO 4401 standard)
- Fluid cleanliness: ISO 4406 class 20/18/15 or cleaner recommended
- Temperature range: -20°C to +80°C (fluid), -20°C to +70°C (ambient)
- Sealing material: Typically NBR (nitrile rubber)
- Requires proper bleeding during commissioning
- Regular inspection of electrical connections and fluid quality
- Compatible with standard subplates (ISO 4401-03-02-0-94)
