Flomatic Cast Iron 1 1/4" Ball Check Valve
SKU: VA-172141
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).
- Cast iron body with epoxy coating and clean-out port.
- Nitrile (Buna-N) Sinking Ball.
- Max Temperature 180°F (80°C).
- Max Pressure 150 PSI.
Do NOT subject ball check valves to freezing conditions.
Thread Sealants: Teflon Tape or Paste?
Teflon tape is a quick and clean way to seal threads in most applications. When applying Teflon tape, care must be taken to apply the tape correctly or leaking may still occur. You should wrap the thread 2-3 times around the threads in a counter-clockwise direction so that the tape doesn't bunch up when it is screwed into the pipe. Do not over tighten, as this may cause the tape to become thin or break in spots, while under tightening may allow water through.
For professional, long-term or industrial applications, Teflon paste, although messy and more difficult to apply, will provide a more reliable seal that won't leak if the plastic pipe distorts over time. Teflon paste should be applied to both the male and female threads.
