The "10" prefix typically refers to a specific component series or size classification within the product family. It may indicate a particular valve size, flow capacity, or performance category. Always refer to the product catalog for detailed specifications of the 10 series.
PU1 typically indicates a performance enhancement package that may include improved response characteristics or additional features. -37 suffix often refers to optimized control characteristics for specific applications, while -38 usually denotes enhanced electromagnetic compatibility (EMC) protection. The exact specifications for each suffix should be verified in the product documentation.
With integrated position feedback and closed-loop control, these valves typically achieve pressure control accuracy within ±1-2% of full scale under standard conditions. Actual accuracy may vary depending on system conditions, amplifier performance, and calibration.
Standard models with NBR seals are primarily designed for mineral-based hydraulic oils. For water-glycol or other water-based fluids, special seal materials (such as FKM or EPDM) may be required. Always consult the product documentation for fluid compatibility and contact technical support for specific fluid recommendations.
Under normal operating conditions with clean hydraulic fluid, these valves require minimal maintenance. Periodic inspection of seals, electrical connections, and valve performance is recommended every 12 months or 2000 operating hours. In harsh environments or with contaminated fluid, more frequent inspection may be necessary.
All models are available through authorized distribution channels. When ordering, please provide the complete model number including all suffixes. Standard delivery time is 4-6 weeks for standard configurations. Custom options may require additional lead time.
Note: Specifications are subject to change without notice. Always consult the latest product documentation for technical details and application guidelines.
