Self-operated control valves, or self-acting pressure regulators, function without auxiliary power by utilizing the energy of the medium itself. These valves are used for controlling temperature, pressure, flow, and differential pressure in applications where deviations from the set point are acceptable and the set point remains stable over time. Their reliability and cost-effectiveness make them ideal for gas, water, and heat networks, where they serve as efficient safety equipment, particularly in systems that would otherwise require expensive auxiliary power supplies.
