Frequently Asked Questions
What is the main difference between A2FE80 and A2FE90 models?
The primary difference is displacement: A2FE80 models have 80 cm³/rev displacement, while A2FE90 models have 90 cm³/rev. This means A2FE90 motors can deliver approximately 12.5% higher torque at the same pressure, making them suitable for appliions requiring more power. Physical dimensions and mounting may be similar, but torque output and flow requirements will differ.
What does the "VZL192J-K" suffix indie compared to other suffixes?
The "VZL192J-K" suffix typically indies a special configuration with specific porting, sealing, or mounting features. The "192" number may refer to a specific design variation, while "J" and "K" suffixes often indie special sealing arrangements or enhanced features. This configuration may be optimized for specific appliions or system requirements. Always refer to the specific product datasheet for exact configuration details.
What does the "VAL100" suffix mean, and how does it differ from "VAL027-S"?
The "VAL100" suffix likely indies a different porting arrangement, connection size, or internal configuration compared to "VAL027-S". The numerical values (100 vs 027) typically refer to specific port sizes, mounting dimensions, or design variations. "VAL" generally indies standard open circuit configuration, but the numerical suffix determines the exact specifiions. Always consult the manufacturer's documentation for precise differences.
Can these motors operate at speeds below 100 rpm?
While the recommended continuous operating range is 100-2800 rpm, some models may operate at lower speeds for intermittent periods. However, operation below 100 rpm may result in reduced efficiency, increased wear, and potential lubriion issues. For continuous low-speed operation, consult the manufacturer for specific recommendations or consider using a gear reduction unit.
How do I determine the hydraulic flow requirements for these motors?
Flow requirement (L/min) = Displacement (cm³/rev) × Speed (rpm) ÷ 1000. For example, an A2FE90 motor at 1500 rpm requires approximately 135 L/min (90 × 1500 ÷ 1000). Actual flow should be slightly higher to account for internal leakage and efficiency losses. Always ensure your hydraulic pump can supply the required flow at the operating pressure.
