Preliminary filters are designed for application in cooling, gas, liquid fuels, solvent, oiland break fluids installations as well as in other installations with non-aggressive media. Filters are used for purifying installation media from pollutants, which prevents systems and equipment from operational incidents and extends their lifespan. They can be either throughway or angle valves, with or without flanges.
The filter cartridge is made of a frame coated with steel, chrome-nickel or other mesh. Additionally, zinc plating makes the cartridge corrosion-proof. Net mesh size: 0.16 – 1 mm, as ordered.
There are also elongated filters that differ from the standard ones in casing height and the length of the filter cartridge, which naturally increases the filtering surface while maintaining the same DN.
Flangeless valves are equipped with connector pipes with dimensions in accordance with PN-80/H-74219 norm and with DIN 2448 standard (marked additionally with symbol:/D).
