Product Description:
PARKER hydraulic valves are widely used in the industrial field due to their high-precision control, durability and strong adaptability. The following are its main advantages and precautions for use:
Core advantages
High-precision control
Adopting hydraulic proportional adjustment technology, the control accuracy can reach less than 0.5%, and can accurately adjust the flow or pressure. The electro-hydraulic integrated design isolates the electrical and hydraulic systems to ensure stability.
Durability
The valve core is made of carbide with a surface hardness of HRC65 and outstanding wear resistance. It can still maintain stable performance under high temperature and high particle pollution conditions (such as dust environment in thermal power plants).
Environmental adaptability
Supports low temperature scenes of -55℃, and no deformation after 72 hours of temperature change test. Special coating treatment can resist sulfate electrolyte corrosion and is suitable for special media scenes such as garbage trucks.
Structural advantages
The cartridge valve design realizes mass production and simplifies the installation process. The two-way balancing valve structure reduces pressure shock, and the shock-absorbing compensation component buffers hydraulic shock and extends the life of the equipment.
Precautions for use
Media and installation requirements
Must match NAS7 level or above filters to avoid slow movement caused by oil impurities; during installation, strictly follow the fluid flow direction (low inlet and high outlet) to ensure sealing.
Maintenance and care
Regularly check the filter element blockage (NAS7 level or above filter element is recommended), and shorten the maintenance cycle under extreme working conditions. Electromagnetic components must be IP67 grade packaged and stored to prevent moisture.
Fault diagnosis
Supports self-diagnosis of faults in power-off state, and the maintenance cost is 23% lower than similar products. If abnormal movement occurs, first check the filter element status and whether the electromagnetic force is normal.
