Diaphragm valve is a valve with less liquid pools due to the structure of the flow path. But furthermore, by placing at the "minimum liquid pools angle" when piping , it is possible to take full advantage of its characteristics.
The "minimum liquid pools angle" varies depending on the model and nominal diameter.
Please enquire us to our sales representatives for the details.

[Option]
(1)TOP marking: to indicates an appropriate pipe angle.
(2)Pipe bolt-hole positions for the TOP marking.

(Installing the product with the "TOP" marking facing directly upward provides the suitable angle for smallest liquid pool.)
