Product Description
Hydraulic support auxiliary valves seamlessly integrate cutting-edge technology, delivering unparalleled performance and reliability based on the technical details provided:
• Material: stainless steel, renowned for its strength and enduring performance.
• Precision Accuracy: Available options of 25/40/80, ensuring meticulous filtration and protection for your system.μm
• The filter element is a critical component of the filter, expertly purifying the emulsion entering the hydraulic support. Its role is to shield the hydraulic valve from blockages caused by impurities, thereby ensuring the seamless and efficient operation of the hydraulic system. Given its susceptibility to wear, regular cleaning and timely replacement of the filter element are essential to maintain peak system performance.
