Flomatic Cast Iron 1 1/4" Ball Check Valve
This 1 1/4" Flomatic ball check valves is designed especially for use with sewage pumps and applications involving viscous liquids or slurries. The principle of the ball check valve is very simple. The ball has sufficient weight to seat tightly even in high viscous liquid, but to open freely so that the headloss is minimal. Flomatic ball check valves can be installed horizontally or vertically provided that they are installed as the installation illustration shows.
The preferred installation of a ball check is in the vertical position. This will insure that gravity will seat the ball properly each time. However, if the ball check valve is to be used in a horizontal installation, it is important that the static head is at least 20 feet of water (nine pounds per square inch).
