Threaded ball check valve for sewerage under pressure and other applications, coupling Du 25-080 Ru 16 ABRA-D022S-NBR. Ball check valves ABRA-D-022S-NBR are used to protect pipelines from the reverse flow of the working medium.
Application:
Designed for sewer, including storm systems, pipelines transporting wastewater, technical hot, cold water, and other liquids.
Installation:
The check valve is not intended to be used as a shut-off valve. Tightness class - AA 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 valves are not subjected to undue mechanical stress during installation. The valve is installed on the pipeline so that the arrow on its body coincides with the direction of medium movement. The valve can be installed in both vertical and horizontal sections of the pipeline, according to the indications of permitted and prohibited positions in the installation (see above). It is required to provide sufficient space around the check valve for future maintenance work.
Working environment:
Waste water, technical hot water, cold water, etc.
