Used for field piping pump station small piping remodeling

The cooling water piping (small piping) was divided into two, and we wanted to individually adjust the distribution flow rate, so we added a gate valve. When the gate valve is fully opened, the valve passage diameter is almost 100% of the pipe cross sectional area, so the pipe friction resistance is zero when fully opened. Resistance infinity with fully closed. At the intermediate opening degree, tube friction resistance changes in proportion to the opening degree, so it was optimal for flow rate adjustment.
