DOROT CXSD

DOROT CXSD, is a 2-way, Diaphragm-actuated, Spring-loaded, Differential Pressure Sustaining Pilot Valve, designed to control hydraulic valves. The pilot valve modulates to keep a steady, preset differential pressure between two points in the water system.
Operation principle
As the differential pressure rises above the preset value, the pilot opens to allow water flow between "COM" and "OUT" ports, thus, allowing water in the main valve chamber to be vented downstream; causing the main valve to open. As the differential pressure falls below the preset value, the pilot throttles the internal passage, restricting flow out from the main valve control-chamber; restricting valve opening, or causing closure, if necessary.
