SIPOS Aktorik 7 Series High Torque Multi-turn Electric Actuator with Chinese Brand Control Valve for Steam Turbine
The Bypass Valve with SIPOS 7 Electric Actuator is a high-precision flow control solution combining a robust globe or butterfly bypass valve with the advanced SIPOS 7 variable-speed electric actuator. Featuring frequency-controlled positioning with ±0.1% accuracy and integrated fieldbus communication (Profibus DP, Modbus RTU), it enables seamless integration into modern DCS and SCADA systems. The SIPOS 7 offers soft start/stop, emergency shutdown (ESD), and comprehensive diagnostics via its color graphic display. Ideal for turbine bypass, pump minimum flow, and pressure reduction stations in power plants, water networks, and chemical processes, this assembly ensures reliable, energy-efficient operation with minimal maintenance.
