Fig.550 is a specially developed electrical actuators based on many years of experience in valve control applications. With compact deisgn, high structural strength as well as large output torque (20Nm~5000Nm), Fig.550 electric actuators offer users very reliable working performance.
With the outstanding design of actuators and our good service team, Coreline expect to provide our customers a complete set of automatic valve control system, as wells as effective mounting/adjusting and on-site service.
Structure and Torque：Compact design, high-strength structure, light weight with large output torque (20NM~5000NM).
Torque and Limit Protection：Electronic torque protection device provides overload protection. Limit switch can adjust the maximum rotation angle required by valve.
Motor Performance：Whole sealing squirrel-cage type motor with compact design, large torque and low inertia. F class insulation. Overheat protection prevents motor from damage by overheating.
Standard Configuration (Heater)：All sizes are equipped with space heater as standard: to prevent condensating inside the motor under big temperature difference so as to keep the internal electric components function properly.
Housing Material and Protection：Hard anodized aluminum alloy body with polyester powder coating to achieve superior anti-corrosion with a protection grade IP67. Meet the design of Exd IIBT4. Can be used in various working environments.
Housing Sealing Design：Body sealing with anti-off design by using stainless steel material, applicable to various working conditions.
Mounting Adaptability：Mounting pad conforms to ISO5211 standard. Spline shape drive shaft design makes it easy for installation for different kinds of valves.
Limit Switch：With both mechanical and electronic limit switch, easy and accurate to operate to the right position.
Observation Window Design：Multi-angle window design: easy for remote observation of the valve position, especially when the valve is mounted at high altitude.
Gear and Handwheel：High precised casting worm gear and handwheel: provide self-locking function and anti-reverse rotation; make it easy for manual operation.
Terminal BlocksSpring-pressed terminals makes it easy for wiring, can be used in high-vibration environment.
