SWV-P11,12,22 (Pressure Reducing Valve):

A diaphragm-type pressure reducing pilot is installed on the main valve, maintaining constant outlet pressure regardless of variations in inlet flow and pressure.

Since this is a pilot operated valve, the capacity is relatively larger than direct acting type valves.

As the springs per each of the controlled pressure range are densely subdivided, minute pressure adjustments are possible.

In addition, pressure adjustments due to changes in operation condition can easily be performed on site.
