The grooved check valve is used in fire protection pipelines and connects via grooved couplings. The silent check valve is suitable for water supply and drainage pipelines. The valve flap uses a central axis guide from both import ends, which allows for flexible operation and can be installed horizontally or vertically. The valve flap uses a spring, and its rapid closure can eliminate water hammer, with good sealing performance. It has the advantages of small size, light weight, low fluid resistance, wear resistance, and long lifespan. The grooved check valve is installed in water supply and drainage, fire protection, and heating systems, and is also used at the outlet of water pumps to prevent backflow from damaging the pump.
