Description
Purpose and scope
Filters designed to protect pipeline systems from the ingress of foreign particles. The filter is installed before the protected element, captures and collects all solid particles whose size exceeds the cell size of the filter element. The filter can be installed in the pipeline in horizontal position and vertical position. The direction of flow in the pipeline must match the direction indicated by the arrow on the filter housing. For vertical installation the direction of flow should be from top to bottom.
Joining to the pipeline – weld or flanged.
Used on pipelines for cleaning oil, water (hot and cold), compressed air, technical gases and other environments. Environment is transported in pipelines must meet the NTD.
Filtering element:
- Steel 12KH18N10T stainless steel mesh size according to customer's requirement.
- Other types of filter elements according to customer's requirement, including filter elements of plane type.
In case of clogging of the mesh filter element, remove the cover, remove filter element and wash it in warm water.

Decoding a symbol of filter mesh:
Filter mesh ФВД2..B.In.G-D, where:
FVD – type of rebar – a "filter mesh";
А – weld (P), flanged (F);
B – nominal diameter of DN– 015, 020, 025, 032, 040, 050, 080, 100, 125, 150, 200, 250 mm
В – nominal pressure PN– 100, 160, 250, 320, 420 kgf/cm2;
G – material case and flange – NJ – 12X18H10T (14KH17N2), With – steel 20, CL – 09G2S;
D – the cell size in the grid, in mm;
An example entry designation filter mesh DN 80 PN 160, alloy steel 09G2S with a cell size in a grid of 1.2 mm with weld ends:
