Frequently Asked Questions
What is the difference between "10" and "1X" in the model number prefix?
The "10" and "1X" prefixes typically refer to different component series or size classifications. The "10" series may indicate a specific size or flow capacity category, while "1X" may represent a different series with potentially different performance characteristics. Always refer to the product catalog for detailed specifications of each series.
What does the "-41" suffix indicate in the model number?
The "-41" suffix typically indicates enhanced electromagnetic compatibility (EMC) features. This option provides improved resistance to electromagnetic interference, making the valve suitable for applications in electrically noisy environments or where EMC compliance is required.
Can DBETX series valves be used in closed-loop control systems?
The DBETX series typically does not include integrated position feedback (LVDT), so they are generally used in open-loop control applications. For closed-loop control requiring position feedback, the DBETBX series with LVDT is recommended. Always check the specific model's technical data sheet for feedback capabilities.
What is the typical hysteresis for these proportional valves?
Standard DBETBX models with position feedback typically have hysteresis less than 3% of full scale, and can achieve below 1% with proper closed-loop control. DBETX series without feedback may have slightly higher hysteresis. The exact value depends on the specific model and system conditions.
Are these valves compatible with both 0-10V and 4-20mA input signals?
Most models support both signal types, but the specific compatibility depends on the internal electronics and the connected amplifier. Some models may require external signal conditioning or specific amplifier cards. Always refer to the product documentation for signal compatibility requirements.
