DOROT CXAL, is a High-sensitivity, 2-way, Diaphragm-actuated, Spring-loaded, Pressure Reducing Pilot Valve, designed to control hydraulic valves. The pilot valve modulates to keep a steady, preset downstream pressure or level in a downstream elevated tank.
Operation principle
As downstream pressure or level falls below a preset value, the pilot opens a full passage between "COM" and "OUT" ports; thus, allowing the main valve to open by venting the control chamber pressure to the downstream. As downstream pressure rises above the preset value, the pilot valve throttles the internal passage, restricting the flow out from the main valve control chamber; causing the main valve to maintain its position or to close, if necessary.
