Asahi AV Ball Foot Valve

- Check valves are not recommended for use with sewage or drainage water, as their non-return performance may be impaired if foreign matter or slurry is mixed in.
- Check valves may leak if the back pressure is low and the non-return effect is not achieved. The back pressure required to stop water flow varies depending on the nominal diameter and seal material.

- It can be used for both horizontal and vertical piping, but please align the arrow on the valve body with the direction of the fluid flow when piping.
- Avoid using it in a line where the fluid flow is severely turbulent. The ball may swing inside the valve, causing damage.
- Use AV swing check valves near pumps with unstable fluid flow.
- If you select PP for the body material, the ball will also be PP, so it may not be possible to completely seal due to the specific gravity.

By manufacturing the screen as a single unit, there are no more adhesive parts as with conventional products, improving the reliability of strength. The flow path has a structure with low fluid resistance, and the valve has low pressure loss. With a small number of parts and only one connection point, it is less susceptible to external stress, and the high finishing precision shuts out backflow. It is lightweight and compact, so it can be easily installed in narrow spaces, and its structure allows for easy disassembly and cleaning.
