Application:

Cold water supply (CWS), hot water supply (DHW), heat supply with any standard heat carrier (including antifreeze), steam systems (steam lines, steam lines) up to 200°C, Condensate lines, process water supply, neutral and inert gas pipelines, water treatment and water intake , transportation of mineral and synthetic oils, etc.

Installation:

The check valve is not intended to be used as a shut-off valve. Tightness class - B according to GOST 54808-2011. Before starting operation, the pipeline must be blown to remove scale and dirt. Piping alignment and flange spacing should be within 3-5 mm of ideal so that the valve is not subjected to undue mechanical stress during installation. The valve can be installed on vertical, inclined and horizontal sections of the pipeline. The valve is installed on the pipeline so that the arrow on its body coincides with the direction of movement of the medium, and, to ensure uniform wear during operation, no closer than 3-5 diameters before or after narrowing / turning. Make sure there is enough space around the check valve for future maintenance work. Before mounting, carefully clean the sealing surfaces of the non-return valve and the connecting flanges. The fixing bolts must be tightened evenly.

Working environment:

Water, incl. marine, salt solutions, steam (up to 8 bar), compressed air, neutral gases, alcohols, antifreezes incl. water-glycol, slightly aggressive media, light and dark oil products, etc.
