Frequently Asked Questions
Q: What is the key difference between the 200 bar and 100 bar versions of this valve?
A: The primary difference is the pressure rating. The "200" in the model number indicates a 200 bar pressure setting, while "100" indicates 100 bar. This means the 200 bar version is designed for higher pressure applications. The internal spring and pressure adjustment range are calibrated accordingly. All other mechanical and electrical specifications remain essentially the same.
Q: Can I adjust the pressure setting beyond 200 bar?
A: No. The valve is factory-set and calibrated for a maximum pressure of 200 bar. Attempting to adjust it beyond this range may damage internal components, void the warranty, and create safety hazards. The maximum working pressure of the valve body is 420 bar, but the proportional control range is limited to 200 bar. For higher pressure requirements, select a valve with the appropriate pressure rating.
Q: What should I check if the pressure doesn't reach 200 bar?
A: First, verify that the input control signal is reaching the maximum value (e.g., 10V or 20mA). Check electrical connections and the external amplifier. If the signal is correct but pressure is low, inspect for internal leakage (damaged seals), contamination causing spool sticking, or possible spring fatigue. Also ensure the hydraulic pump can deliver sufficient flow and pressure to the system.
Q: Is this valve suitable for phosphate ester fluids?
A: No. The "M" suffix indicates NBR seals, which are not compatible with phosphate ester fluids. NBR seals are designed for standard mineral-based and synthetic oils. For phosphate ester applications, you would need the "V" version (DBET-61/200YG24K4V) with FKM seals. Using the wrong seal material with phosphate ester can cause seal swelling, degradation, and failure.
Q: What are the installation requirements for the 200 bar version?
A: Ensure all system components (pipes, hoses, fittings, and other valves) are rated for at least 200 bar working pressure. Use proper mounting torque on the subplate connections (refer to manufacturer's specifications). The hydraulic system should be clean (ISO 4406 18/16/13 or better) to prevent contamination damage. Provide a stable 24V power supply and proper grounding for the electrical connections.
