Operating Principle
Frequently Asked Questions (FAQ)
Q
What is the nominal operating pressure of the load-sensing valve?
The nominal operating pressure of the load-sensing valve is 250 bar. The maximum pressure at ports A and B can reach up to 280 bar, ensuring reliable performance in demanding hydraulic systems.
Q
What is the maximum flow rate supported by the valve?
The maximum flow rate is 100 L/min per unit. This makes the valve suitable for high-performance hydraulic circuits requiring efficient flow management.
Q
What hydraulic oil temperature range is acceptable for this valve?
The valve is designed to operate within a hydraulic oil temperature range of -20°C to +100°C, making it suitable for both cold-start environments and high-temperature industrial applications.
Q
What oil cleanliness level is required for proper valve operation?
The recommended oil contamination level is -/19/16 according to ISO 4406:1999. Maintaining proper oil cleanliness is essential to ensure long service life and prevent premature wear of valve components.
Q
What are the pressure settings for the primary and secondary relief valves?
The primary relief valve pressure range is 100–250 bar, while the secondary relief valve can be set between 150–315 bar. These adjustable settings allow flexible integration into various hydraulic system configurations.
Q
What is the viscosity range and total weight of the valve unit?
The acceptable hydraulic fluid viscosity range is 10–460 mm²/s, accommodating a wide variety of hydraulic oils. The total weight of the valve assembly is approximately 35 kg.
