Introduction of duplex filter working                                                                                                                     

 Induction:  Duplex oil return filter SYLQ-BL series is made of two monocular and a change valve . mating BLLX series unite type filter element . The structure of filter simpleness , convenient to use , and with balanced valve and differential pressure send message receptor , in order to reach ensure system security .

working principle: There is only one filter to operation in normally work . You can not stop the system then open the pressure balance valve and roll reversing vales .switch to another filter to work , when the filter pressure loss exceed(more than 0.35 MPa ) and then clean or replace the filter element . 

Applition:  This filter is widely used in metallurgical machinery , mining machinery , heavy-duty machinery etc hydraulic system.
