Product Overview
This valve is mainly used at the outlet of pipeline pumps in water supply and drainage systems, fire protection, air conditioning, electricity, construction, food, water treatment, municipal administration, shipbuilding, and other pipelines to prevent the backflow of media. Since the sealing ring of this product adopts an inclined design, the closing time is short, which can reduce water hammer pressure. The valve disc is made of nitrile oil-resistant rubber and a steel plate that is pressed at high temperatures. It has good erosion resistance and sealing performance. The product structure is simple, and maintenance, repair, and transportation are easy.
