A self-operated pressure regulator is a device used to automatically control and maintain a desired pressure level in a system without the need for external power or control signals. It operates based on changes in pressure within the system.
A self-operated pressure regulator consists of a sensing element, a control valve, and a pressure spring. The sensing element, typically a diaphragm or piston, reacts to variations in system pressure. When the system pressure exceeds the setpoint, it compresses the spring, causing the control valve to close and reduce the flow rate. Conversely, when the system pressure falls below the setpoint, the spring expands, causing the control valve to open and increase the flow rate.
Self-operated pressure regulators are commonly used in applications where there is a need to maintain constant pressure, such as in steam systems, heating systems, and water distribution networks. They provide a cost-effective and reliable solution for pressure control without the need for external control or power sources.
