Ball type sewage check valve

1:Ball type sewage check valve is also called slide ball type check valve. The sealing element is a ball covered with rubber, so it has good sealing          performance, reliable operation and good water hammer resistance. Moreover, since the seal can be single ball or multi ball, it can be made into          large diameter. However, its seal is a hollow ball covered with rubber, which is not suitable for high pressure pipeline, but only suitable for soft              sealing valve pipeline of medium and low pressure.

2.The valve body of the ball type sewage check valve is cast once, and the valve disc is sealed with cast iron ball rubber. Driven by the medium, the      valve disc can roll up and down on the slide way of the valve body, playing the role of opening and closing the valve. It has the advantages of large      flow, small resistance, good sealing performance, long service life and no water hammer. It can be installed horizontally or vertically It is used in          industrial and domestic sewage pipe network with high viscosity and suspended solids.

3.Ball type sewage check valve is a special check valve for sewage treatment plant, industrial sewage and domestic sewage pipe network, suitable      for submersible sewage pump. The medium temperature of ball type sewage check valve is 0-80 ºC. Cast iron ball coated with rubber is suitable for    sewage, and it is a special check valve for sewage pipe drainage.
