Description:

Pressure filters, change-over series DNA 1050-2050 are suitable for operating pressure up to 232 PSI. Pressure peaks can be absorbed with a sufficient margin of safety.
Change-over ball valve which, integrated in the middle of the housing, makes it possible to switch from the dirty filter-side to the clean filterside without interrupting operation.
The filter element consists of star-shaped, pleated filter material which is supported on the inside by a perforated core tube and is bonded to the end caps with a high-quality adhesive. The flow direction is from outside to the inside. These filters can be installed as suction filters.
Filter finer than 40 μm should use throw-away elements made of paper or Interpor fleece (glass fiber). Filter elements as fine as 5 μm(c) are available; finer filter elements on request.
INTERNORMEN-Filter elements are known as elements with a high intrinsic stability and an excellent filtration capability, a high dirtretaining capacity and a long service life.
INTERNORMEN-Filter are suitable for all petroleum based fluids, HW-emulsions, most synthetic hydraulic fluids and lubrication oils.
Approvals according to TÜV, and the major „Shipyard Classification Societies“ D.N.V.; B.V.; G.L.; L.R.S.; R.I.N.A.; A.B.S. and others are possible.
The internal valve is integrated into the filter. After reaching the opening pressure the by-pass valve causes that an unfiltered partial flow passes the filter.
