Technical details and manufacturing context for Regulating Valve (Actuator)

Definition
This regulating valve actuator is a component used in industrial process control systems. It is part of a pressure regulation module and is designed to precisely adjust the opening of a valve to regulate fluid pressure, flow rate, or other process variables. The actuator converts control signals into mechanical motion to position the valve stem, thereby altering the flow area through the valve. It is available in configurations suitable for nominal diameters from 15 to 300 mm (per ISO 6708) and offers a flow coefficient (Cv) range of 1.6 to 1200 m³/h (per IEC 60534-2-1). The rated stroke can be linear or rotary, ranging from 10 to 100 mm (per IEC 60534-4). Control accuracy, defined as the positioning error of the valve stem, is within ±0.5% to ±2.0% (per IEC 60534-4). The actuator can be powered pneumatically with supply pressures from 0.3 to 0.7 MPa or electrically with a 24 V DC supply (per IEC 60038). It accepts analog input signals of 4–20 mA (per IEC 60381-1). Operating temperature ranges from -40°C to 85°C (per IEC 60534-4), and operating pressure is 1.0 to 1.6 MPa. Leakage class is IV to VI (per IEC 60534-4). Body materials include carbon steel (WCB) to stainless steel (CF8M) per ASTM A216/A351. Weight varies from 5 to 500 kg depending on size and actuator type. Enclosure protection for electric actuators is IP54 to IP65 (per IEC 60529). Materials used include stainless steel, aluminum alloy, and engineering plastics. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.
Working Principle
The actuator receives electrical, pneumatic, or hydraulic control signals and converts them into mechanical force to position the valve stem. This movement adjusts the flow area through the valve, thereby regulating the pressure or flow rate of the fluid. The control signal is typically a 4–20 mA analog signal for electric actuators, or a pneumatic supply pressure for pneumatic versions. The actuator's positioner compares the actual valve position to the desired setpoint and adjusts the force to minimize error, achieving the specified control accuracy. The mechanical motion can be linear (for globe valves) or rotary (for ball or butterfly valves), depending on the valve type. The actuator must be selected based on the required stroke, force, and response time to match the process dynamics.
