Q: What is the maximum pressure this valve can be set to control?
A: The "315" in the model number indies that this valve is calibrated for a maximum set pressure of 315 bar. The valve body itself can withstand a maximum operating pressure of up to 420 bar, but the proportional control range is specifically designed for 315 bar. Attempting to set it beyond this calibrated range is not recommended and may affect performance and safety.
Q: What do the "M" and "K4" codes in the model number mean?
A: The code "M" specifies that the valve is equipped with NBR (Nitrile) seals, which are suitable for use with standard mineral-based hydraulic oils (HL, HLP). The code "K4" refers to the electrical connection type, indiing a 3-pole connector without a mating connector, conforming to DIN EN 175301-803.
Q: Does this valve include an integrated amplifier, or is an external unit required?
A: The DBET-61/315YG24K4M requires an external control amplifier (e.g., VT-MSPA1-2X series) for operation. The valve's proportional solenoid needs an external electronic unit to provide the precise control current (0-1600 mA) based on a command signal (e.g., 0-10 V) to accurately adjust the pressure.
Q: What is the maximum flow rate for this 315 bar model?
A: For the DBET-6X series with pressure ratings of 315 bar and above, the maximum flow is limited to 2 liters/minute to ensure stable and accurate pressure control. Exceeding this flow at high pressure settings can impact performance.
Q: What maintenance is crucial for ensuring the long-term reliability of this valve?
A: The most critical maintenance practice is maintaining hydraulic oil cleanliness (recommended ISO 4406 class 20/18/15 or better) to prevent contamination from causing spool sticking or internal damage. Regularly checking electrical connections for corrosion or looseness and inspecting for external leaks around the seals are also essential for reliable operation. For optimal performance, ensure the hydraulic fluid temperature remains within the operating range of -20°C to +70°C.
