Frequently Asked Questions (FAQ)
Q
What is the maximum operating pressure for ports A and B of the load-sensing valve?
The maximum operating pressure for ports A and B is 315 bar, while the nominal system pressure is 250 bar.
Q
What type of connection does this valve use?
This load-sensing valve uses a threaded connection with a nominal diameter of 20 mm. Please refer to the technical drawing for the exact mounting method.
Q
What is the allowable hydraulic oil temperature range 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 a wide range of environmental and operational conditions.
Q
What oil cleanliness level is required for proper valve operation?
The permissible oil contamination level is -/18/15 according to ISO 4406:1999. Maintaining this cleanliness level is essential to ensure reliable and long-lasting valve performance.
Q
What are the pressure settings for the primary and secondary safety valves?
The primary safety valve can be set within the range of 100–200 bar, and the secondary safety valve within 150–315 bar. These settings allow flexible adaptation to various hydraulic system requirements.
Q
What is the maximum flow rate and total weight of the valve?
The maximum flow rate is 160 l/min per unit. The total weight of the valve assembly is approximately 70 kg (7 per set), making it suitable for heavy-duty industrial and mobile hydraulic applications.
