Frequently Asked Questions
Q1: What is the difference between the 1.6A, 2.5A, and 3.7A coil versions?
A: The coil current rating affects the valve's response speed and the required amplifier output capability. Higher current coils (3.7A) provide faster response times but require amplifiers with higher current output. Lower current coils (1.6A) are suitable for standard applications and are compatible with most standard amplifiers. The 2.5A version offers a balance between performance and amplifier requirements.
Q2: Can these valves be used in closed-loop control systems?
A: Yes, all models feature integrated LVDT position feedback, making them suitable for closed-loop control applications. This allows for precise pressure control with reduced hysteresis and improved accuracy.
Q3: What is the typical pressure setting range for these valves?
A: The proportional control range is typically from 5% to 95% of the maximum rated pressure. For example, a 315 bar valve can be set between approximately 15 bar and 300 bar. The exact minimum and maximum settable pressure may vary depending on the specific model and system conditions.
Q4: Are these valves suitable for use with water-based hydraulic fluids?
A: Standard models with NBR seals are designed for mineral-based hydraulic oils. For water-based fluids (HFA, HFB, HFC), special seal materials may be required. Please consult the product documentation for seal compatibility with specific fluids.
Q5: What is the meaning of the "1X" in the model number?
A: The "1X" designation typically refers to the component series or size classification. In this series, it indicates a specific valve size and flow capacity category. The exact meaning may vary by manufacturer, so refer to the product catalog for detailed specifications.
