Explore how PRVs operate, where they deliver the greatest benefits, and how to select and adjust the right model for each hydraulic scenario
DOROT S90 PR/M (3W), is a Weir-type diaphragm, 3-way, automatic, pilot-controlled, pressure reducing globe valve, with a selector valve for manual override. The valve reduces high upstream pressure to a steady, preset, lower downstream pressure; regardless of fluctuations in upstream pressure or flow rate. In cases where the downstream pressure exceeds the set value, the valve will close drip-tight.
