Frequently Asked Questions
1. What is the maximum pressure this valve can be set to control, and what does the "350" indicate?
The "350" in the model number indicates that this valve is calibrated for a maximum set pressure of 350 bar. This is the highest standard pressure rating in the DBET-6X series for this size. The valve body can withstand a maximum working pressure of up to 420 bar, but the proportional control range is specifically designed for 350 bar. Do not attempt to set it beyond this calibrated range.
2. What hydraulic fluids are compatible with this model?
The DBET-61/350YG24K4M with NBR seals is compatible with standard mineral-based hydraulic oils (HL, HLP) and synthetic fluids (HETG, HEES). The "M" suffix indicates NBR seals, which are not suitable for phosphate ester fluids or water-based fluids. For phosphate ester applications, you would need the "V" version with FKM seals.
3. What is the maximum flow rate for this 350 bar model?
For the DBET-6X series with 350 bar pressure rating, the maximum recommended flow rate is 2 liters/minute to ensure stable pressure control and prevent performance degradation. Exceeding this flow at high pressure settings may cause pressure instability or reduced accuracy.
4. Does this valve require an external amplifier, and what electrical connections are needed?
Yes, this valve requires an external control amplifier (such as VT-MSPA1-2X series) to operate. The valve receives a 24V power supply and a proportional control signal (0-10V or 4-20mA) through its 3-pole connector (DIN EN 175301-803, "K4" designation). The amplifier converts the command signal to the appropriate current for the proportional solenoid.
5. What are the key installation and maintenance considerations for this high-pressure valve?
For installation, ensure all system components (pipes, hoses, fittings) are rated for at least 350 bar working pressure. Use proper mounting torque on the subplate connections. For maintenance, the most critical factor is maintaining hydraulic oil cleanliness (ISO 4406 class 20/18/15 or better recommended). Regularly check electrical connections for tightness and corrosion, inspect for external leaks, and verify pressure response characteristics. For systems operating at high pressures, more frequent inspections are advised.
