Strainer Questions

Tell me about the piping posture of a Y-strainer.: Install a Y-strainer so that the screen faces downward.

・In the case of horizontal piping, connect the piping so that the cap or cover faces downward as shown in the figure.
・When the fluid is descending in vertical piping, connect the piping so that the cap or cover faces downward as shown in the figure. When the fluid is ascending, provide a horizontal piping section to connect the piping.

If the strainer is installed in the reverse position, foreign matter and dust may flow back into the primary piping, so it is not recommended.

Tell me the characteristics of a U-strainer.: A U-strainer is easy to clean because the screen is removed from above after removing the top cover. Therefore, it can be used in lines where maintenance space is not available with a Y-strainer in floor piping.
However, please note that the installation posture is only for horizontal piping.
