Frequently Asked Questions
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.
What does the "315" in the model code indicate?
The "315" specifies the maximum pressure setting capability of 315 bar. This is the highest pressure range available in the DBEBE series for NG6 size valves. The valve can be electrically adjusted to regulate pressure from 0 to 315 bar.
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 (K31 type)
- Requires compatible proportional amplifier
What does the "A1M" suffix indicate?
The "A1M" typically refers to specific sealing material and coil configuration. "A" may indicate standard nitrile rubber (NBR) sealing material, while "1M" may denote a specific coil variant or mounting configuration. Always check the manufacturer's documentation for exact material specifications.
How does this model differ from the 180 bar and 80 bar versions?
The key difference is the pressure setting range: this model has a 0-315 bar range, while the 180 bar and 80 bar versions are limited to their respective pressure ranges. All other core parameters (size, voltage, current, port size) remain identical. The 315 bar version is designed for high-pressure hydraulic applications.
What are the installation and maintenance considerations for high-pressure applications?
- Port size: NG6 (ISO 4401 standard)
- Fluid cleanliness: ISO 4406 class 20/18/15 or cleaner recommended (critical for high-pressure systems)
- Temperature range: -20°C to +80°C (fluid), -20°C to +70°C (ambient)
- Sealing material: Likely NBR (nitrile rubber) based on "A" code
- Requires proper bleeding during commissioning
- Regular inspection of electrical connections and fluid quality
- High-pressure systems require additional safety precautions — ensure all connections are rated for 315 bar
What are the typical applications for this 315 bar model?
This high-pressure model is suitable for applications requiring precise pressure control in high-pressure hydraulic systems, such as:
- Industrial machinery with high-pressure hydraulic circuits
- Press machines and forming equipment
- Injection molding machines
- Test stands and hydraulic test equipment
- Any application where system pressure exceeds 180 bar but requires proportional control
