Design & structural Features
The valve adopts a rubber-coated ball as the disc, which rolls along the internal guide path under the action of the medium to open or close the valve. It provides large flow capacity, low flow resistance, excellent sealing performance, and silent closing, effectively reducing water hammer. The valve can be installed either horizontally or vertically, and is suitable for installation at the pump outlet in pipelines for cold water, hot water, industrial and domestic sewage, preventing reverse flow of the medium.
