FAQ — Frequently Asked Questions
Q1
What is the maximum operating pressure of the load-sensing valve?
The nominal operating pressure is 300 bar. The maximum pressure at ports A and B reaches 400 bar, while the maximum pressure at pilot ports a and b is 35 bar.
Q2
What is the maximum flow rate supported by this valve?
The maximum flow rate is 160 l/min per section. This makes the valve suitable for high-performance hydraulic systems requiring substantial fluid throughput.
Q3
What hydraulic oil contamination level is acceptable for this valve?
The permissible oil contamination level is -/19/16 according to ISO 4406:1999. Maintaining proper filtration is essential to ensure reliable and long-term valve performance.
Q4
What is the operating temperature range for the hydraulic oil?
The hydraulic oil operating temperature range is -20°C to +100°C, allowing the valve to function reliably in both cold and high-temperature environments.
Q5
What are the primary and secondary relief valve pressure settings?
The primary relief valve pressure can be set between 100 and 300 bar, while the secondary relief valve pressure ranges from 150 to 315 bar, providing flexible system protection options.
Q6
How is the valve connected and what is its overall weight?
The valve uses a threaded connection with an 18 mm diameter and is designed as a split-type component. The total weight of the assembly is approximately 42 kg. Installation should follow the dimensions indicated in the engineering drawing.
