duplex return filter
1.element material:stainless steel
2.housing material:cartbon steel
ing pressure:1.6MPa
4.ISO9000

Introduction :

Duplex 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: duplex return filter

It only use a filter unit to process work when it working regularly .  It can open pressure balanced valve and move

 change valve , switch to another filter unite to process work ,then to clean or change filter element which is

banked-up , when the filter unite pressure loss overproof (more than 0.35 MPa).

Use scope:

Duplex return filter is widely used in metallurgical machinery , mining machinery , heavy-duty machinery

etc hydraulic system.
