Frequently Asked Questions
What is the main difference between DBETBX-10 and DBETX-10 series?
The primary difference is that DBETBX-10 series valves typically include integrated position feedback (LVDT) for closed-loop control applications, while DBETX-10 series are standard proportional relief valves without position feedback. This affects their suitability for closed-loop control systems.
What do the suffix codes -37 and -38 represent?
The -37 suffix typically indicates optimized control characteristics or specific performance parameters for certain applications. The -38 suffix usually denotes enhanced electromagnetic compatibility (EMC) protection, making the valve more resistant to electromagnetic interference in noisy environments.
What is the typical hysteresis for these valves?
DBETBX-10 models with position feedback typically achieve hysteresis below 3% of full scale, and can reach below 1% with proper closed-loop control. DBETX-10 models without feedback may have slightly higher hysteresis. Actual values depend on system conditions and should be verified in the product data sheet.
Can these valves be used with both 0-10V and 4-20mA input signals?
Most models support both signal types, but compatibility depends on the internal electronics and connected amplifier. Some models may require specific amplifier cards or external signal conditioning. Always check the product documentation for signal compatibility requirements.
What is the recommended maintenance interval for these proportional valves?
Under normal operating conditions with clean hydraulic fluid, these valves require minimal maintenance. Periodic inspection of seals, electrical connections, and overall performance is recommended every 12 months or 2000 operating hours. In harsh environments or with contaminated fluid, more frequent inspection may be necessary.
