Operating Principle
Frequently Asked Questions
Q
What is the nominal operating pressure of this load-sensing valve?
The nominal operating pressure is 200 bar. The maximum pressure at ports A and B can reach up to 275 bar, ensuring reliable performance in demanding hydraulic systems.
Q
What type of connection does this valve use?
The valve uses a threaded connection with a diameter of 10 mm. It is a detachable part, and the mounting method should be referenced from the technical drawing provided.
Q
What is the maximum flow rate supported by this valve?
The maximum flow rate is 60 l/min per piece. This makes it suitable for a wide range of hydraulic applications requiring precise flow control.
Q
What hydraulic oil contamination level is acceptable?
The permissible oil contamination level is -/19/16 according to ISO 4406:1999. Maintaining oil cleanliness within this range is essential for long-term valve performance and reliability.
Q
What is the operating temperature range for the hydraulic oil?
The hydraulic oil temperature range is -20°C to +100°C, with a viscosity range of 10–460 m²/s, allowing the valve to operate effectively in various environmental conditions.
Q
What are the pressure settings for the primary and secondary relief valves?
The primary relief valve pressure range is 100–200 bar, while the secondary relief valve pressure range is 100–315 bar. These settings provide flexible and safe pressure protection for the hydraulic circuit.
