A Self-Operated Control Valve is an automatic valve that utilizes the process fluid’s own energy to regulate flow, pressure, or temperature without the need for external power sources. This design simplifies control systems, reduces installation costs, and enhances reliability, making it ideal for various industrial applications.
Energy Efficiency: Operates without external power, relying solely on the process fluid’s energy.
Simplicity: Features a straightforward design with fewer components, leading to lower maintenance requirements.
Reliability: Offers consistent performance due to its autonomous operation and minimal moving parts.
Versatility: Suitable for controlling pressure, temperature, and flow in diverse processes.
Manufacturing Standard: Conforms to standards such as ANSI, ASME, DIN, or JIS, ensuring compatibility and quality.
Structural Length Standard: Adheres to standards like ANSI/ISA-75.08.01 or IEC 60534-3-1 for face-to-face dimensions.
Connection Forms Standards: Meets connection standards such as ASME B16.5 for flanges, ASME B1.20.1 for threaded connections, and ASME B16.25 for welded ends.
Available Sizes (Caliber): Standard sizes range from DN15 to DN300, with custom sizes available upon request.
Pressure-Temperature Rating: Follows ASME B16.34 standards, providing pressure-temperature ratings based on material and design.
Pressure Range: Typically designed for pressures up to 1.6 MPa (16 bar), with options for higher pressures as needed.
Temperature Range: Operates effectively within -20°C to 350°C, depending on construction materials and application requirements.
Steam Systems: Regulates steam pressure and temperature in heating and power generation.
Water Treatment: Controls flow and pressure in filtration and distribution systems.
Chemical Processing: Maintains precise control of process variables in chemical reactions.
HVAC Systems: Manages temperature and pressure in heating, ventilation, and air conditioning.
