Self-operated control valve
Self-operated control valve requires no external power like electricity or air, and automatically adjusts the medium’s pressure, temperature or flow by using the energy of the pipeline medium itself. Made of cast steel, stainless steel and alloy steel, it is suitable for automatic regulation of water, steam, oil, gas and mildly corrosive fluids in petrochemical, metallurgy, electric power, heating and water treatment systems, featuring energy-saving, compact structure, stable performance and reliable sealing, providing economical and effective fluid control for working conditions without external driving sources.
Self-operated pressure regulating valve
The Self-operated Pressure Regulating Valve is a reliable and cost-effective solution for precise pressure control in pipelines without the need for external power sources. Utilizing the energy of the process fluid, it automatically adjusts to maintain set pressure levels, making it ideal for applications in steam systems, gas distribution, and liquid process lines. Its simple design ensures low maintenance and long-term reliability in demanding industrial environments.
Self-operated micro-pressure regulating valve
The Self-operated Micro-Pressure Regulating Valve is a precision-engineered solution designed for ultra-fine pressure control in low-pressure systems. Utilizing the energy of the process fluid, it automatically adjusts to maintain set pressure levels with exceptional accuracy, making it ideal for applications in laboratory equipment, gas analyzers, and precision instrumentation. Its compact design and self-operating mechanism ensure reliable performance without the need for external power sources.
Self-operated temperature regulating valve
The Self‑operated Temperature Regulating Valve is an automatic control valve that requires no external power source (electricity or compressed air). It opens and closes solely by the temperature change of the controlled medium. Its core component is a temperature sensor bulb (thermostatic bulb) and an actuating bellows.
