Frequently Asked Questions
Q
What is the maximum operating pressure for ports A and B of this load-sensing valve?
The maximum pressure for ports A and B is 280 bar, while the nominal operating pressure is 250 bar. This ensures safe and reliable performance under high-pressure hydraulic conditions.
Q
What is the adjustable pressure range for the primary and secondary relief valves?
The primary relief valve can be adjusted within the range of 100–280 bar, and the secondary relief valve within 150–300 bar. This flexibility allows the valve to be configured for various hydraulic system requirements.
Q
What hydraulic oil temperature range is this valve suitable for?
This valve is designed to operate with hydraulic oil temperatures ranging from -20°C to +100°C, making it suitable for both cold-start environments and high-temperature industrial applications.
Q
What is the maximum allowable flow rate per unit?
The maximum flow rate per unit is 100 L/min. This high flow capacity makes the valve well-suited for demanding hydraulic applications requiring efficient fluid control.
Q
What is the recommended oil cleanliness level for this valve?
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 reliable valve performance.
Q
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 port diameter of 14.3 mm. The mounting method is illustrated in the technical drawing provided with the product documentation.
