Product Description:
Advantages and features of Danfoss priority valves
High-precision flow distribution and low energy consumption
Using proportional control technology, the fluid flow and pressure can be accurately adjusted to ensure fast system response speed and high control stability, minimal hysteresis effect, and an error range lower than the industry standard;
Low leakage design (leakage rate ≤ 0.1%), combined with low pressure drop characteristics, significantly reduces energy consumption and improves fuel efficiency, suitable for long-term industrial scenarios.
Dynamic response and environmental adaptability
Support dynamic flow mode, can quickly respond to operating instructions during the startup phase, meet emergency steering or high-precision linkage requirements;
Wide operating temperature range (-30℃ to +100℃) and corrosion-resistant material design, suitable for complex working conditions such as high temperature and high humidity.
Compact structure and low noise operation
Integrated design reduces external pipeline connections and reduces installation complexity; noise during operation is ≤ 65dB, which meets environmental protection and operation safety requirements;
Static and dynamic dual modes are optional, adapting to the flexibility of flow distribution requirements of different systems.
Precautions for use
Installation and commissioning requirements
Ensure that the cleanliness of the hydraulic oil meets the NAS 1638 standard (recommended level 7-9). Before installation, the pipeline needs to be cleaned and a high-precision filter needs to be installed to prevent particulate impurities from damaging the valve core;
During commissioning, the pressure needs to be increased gradually to avoid direct loading of peak pressure (rated pressure ≤ 275bar) to prevent deformation or failure of the seal.
Operation and maintenance specifications
Regularly check the sealing of the valve body and the state of the solenoid coil to prevent leakage or electrical failure; avoid frequent switching of flow direction (switching frequency ≤ 60 times/minute) to extend the life;
During maintenance, it is prohibited to disassemble or adjust internal parameters privately, and it must be operated by professionals. In an emergency, it can be temporarily unlocked through the manual emergency function.
System compatibility and aging management
The priority valve needs to be integrated with a matching control system (such as PLC) to avoid response delays caused by interface incompatibility;
Before long-term deactivation, the residual oil needs to be drained to prevent internal corrosion; and the seals need to be replaced regularly (it is recommended to be checked every 500 hours) to maintain performance.
