The ZU-H, QU-H series pressure linefilter is installed on the pressure pipeline of the hydraulic system to filter out the mechanical impurities mixed in the hydraulic oil and the colloid,asphalt, carbon residue,etc. produced by the chemical change of the hydraulic oil itself,so as to prevent the occurrence of valve core jamming,the blockage of throttle hole gap and damping hole,and the rapid wear of hydraulic components.
The filter is equipped with a differential pressure transmitting device.When the filter element is polluted and blocked until the differential pressure at the inlet and outlet is 035MPa,it will send a signal that the filter element should be cleaned or replaced to achieve the purpose of protecting the system.
