The feature of duplex oil strainer allows for continuous operation when changing elements due to clogging caused by contaminants. After opening the balance valve and turning the directional valve, the other filter begins to work, thus a clogged element should be changed in time.
These series of duplex basket strainer have a high flow range from 1300 l/min to 15000 l/min with maximum pressure 1.6 Mpa. They are widely used in the hydraulic systems of heavy-duty mining and metallurgical machines.
Note: As the leading duplex strainer manufacturer in China , Lilt filter can custom any duplex basket strainers based your detailed requirement.
