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, according to the instructions on permitted and prohibited positions in the installation (installation on a vertical and inclined section of the pipeline with the direction of flow "top-down" is highly undesirable for this type of valves): 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 the narrowing / turning of the pipe. On a horizontal section, it is desirable to install the valve in such a way that the axis (stem) of the valve is set at an angle of 45 degrees to the vertical (horizontal). It is undesirable to install the valve on the bend of the pipeline, but if necessary, you should install it after the bend along the flow and orient the valve axis along the radius of the bend.

Working environment:

Water, any standard coolant (including antifreeze), condensate, etc.
