Non Return Valves

Check valves, or non-return valves, allow water or other material to flow in only one direction, and stop the material from flowing in the opposite direction. They are installed in pipe lines and do not require any activation from outside. Instead, they sense when the material in the pipes is beginning to move in the reverse direction and plug up the pipe to prevent the material's movement.
