Installation of CVL linear actuators at Didcot B Power Station
Rotork最近在Didcot B Power Station安装并委托CVL线性控制阀执行器，该电站向国家电网提供电力。
旋转’s CVL1500 and CVL5000 actuators now control the supply of the spray water that is used as an emergency quench in the condensers should the steam turbine trip. The CVL actuator installation was part of a project to improve equipment reliability and obsolescence of older plant.
RWE在DIDCOT B发电站的平稳运行的这一重要部分中选择了旋转式的旋转，这表明了有效，可靠的驱动技术的重要性。
Didcot B is an efficient combined cycle gas power plant with a net capacity of 1,440 MW approx. power to meet the demands of one million households.
The linear offering of Rotork’s CVA electrically powered process control range, CVL actuators use a 1-phase or DC power supply to provide highly accurate and responsive continuous modulation of control valves.
The CVL units replaced existing hydraulic actuators and now provide improved reliability and reduced maintenance costs.
The CVL ensures extremely accurate flow control with resolution figures better than 0.1% and repeatable positional control using a 4-20 mA signal. It features a thrust range of 890 N to 22,241 N (200 to 5,000 lbf). With an on-board data logger included as standard, the CVL is Bluetooth® compatible for local setup, control and diagnostics. A CVL actuator is perfectly suited for this particular role; they are certified as watertight to IP68 and the terminal compartment is completely sealed, vastly reducing the chance of water ingress.
Several of Rotork’s guiding principles helped secure this order; prompt quotation, fast delivery and full, accurate quotes that perfectly met RWE’s specification needs, in conjunction with the accurate and reliable operation offered by CVL linear actuators.
