Non-welded ASME Filters DA 250, Pressure filters, change-over | |
| |
Description: | |
| Pressure filters, change-over series DA 250 manufactured according
to ASME Code and API Standard 614 are suitable for operating pressure
up to 580 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 filter-side without interrupting
operation. Filter finer than 40 µm should use throw-away elements made of paper or Interpor fleece (glass fibre). Filter elements as fine as 5 µm (c) are available; finer filter elements on request. These filters can also be installed as suction filters. | |
