ZU-H, QU-H series pressure line filter DF series high pressure filter RF Return line Filter SRLF Duplex return line filter

ZU-H, QU-H series pressure line filter

Product Description

The filter 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.

DF series high pressure filter

Product Description

The superimposed filter can be directly installed under the electromagnetic directional valve to remove or prevent the mechanical impurities mixed in the hydraulic oil and the colloid and asphaltene produced by the chemical change of the hydraulic oil from entering the electromagnetic directional valve,so as to prevent the instability or jamming of the valve core and the occurrence of faults such as excessive wear of the valve,and maintain the normal operation of the system.It is especially suitable for automatic control system and servo system.

SRLF Duplex return line filters

Product Description

The filter is composed of two single cylinder drippers and two position six way directional valve.It has the advantages of simple structure and convenient use.It is equipped with by-pass valve and filter element pollution blockage transmitter to ensure the safety of the system.
In the working process,when the filter element of the single cylinder filter is blocked to a certain extent and needs to be cleaned or replaced,stop the main engine to replace the filter element,which not only wastes time,but also can not meet the needs of the continuous operation of the main engine.The double cylinder filter effectively solves the defects of the single cylinder filter,and the filter element can be cleaned or replaced without shutdown to ensure the normal and continuous operation of the main engine.
