Frequently Asked Questions
Q1
What is the maximum operating pressure for ports A and B on this load-sensing valve?
The maximum operating pressure for ports A and B is 315 bar, while the nominal operating pressure is 250 bar. This ensures a reliable safety margin for demanding hydraulic applications.
Q2
What is the maximum flow rate supported by this valve?
The valve supports a maximum flow rate of 160 l/min per unit. For higher flow requirements, multiple units can be combined within the system design.
Q3
What hydraulic oil temperature range is this valve designed to operate in?
This load-sensing valve is designed to operate within a hydraulic oil temperature range of -20°C to +100°C, making it suitable for both cold-climate and high-temperature industrial environments.
Q4
What is the recommended oil cleanliness level for this valve?
The valve requires a hydraulic oil cleanliness level of -/18/15 according to ISO 4406:1999. Maintaining proper filtration is essential to ensure long-term performance and prevent premature wear.
Q5
What is the adjustable pressure range for the primary and secondary relief valves?
The primary relief valve can be set between 100 and 200 bar, while the secondary relief valve is adjustable from 150 to 315 bar. This flexibility allows precise tuning to match specific system requirements.
Q6
What type of connection and construction does this valve use?
The valve uses a threaded connection and features a split-part (разъемная деталь) construction with a nominal diameter of 20 mm. The mounting method is specified in the technical drawing provided with the product documentation.
