Electric Rotary Actuators

Electronic Rotary ActuatorSummary "OMRX" series electric actuator is used to control 0 ° 270 ° rotation of the valves and other similar products, such as butterfly ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, paper making, power plants, heating, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired location, achieving its automation, maximum output torque up to 3000Nm. Shell The shell is made of horniness auminium alloy, pass through anodic oxidation treatment and polyester powder coating, so it has strong corrosion resistance. Electric Machinery Squirrel-cage Asynchronism electric Machinery, small volume, large torque, and small inertia force, F-class insulation rating, Inside hot protection switch, avoid damaging the electric machinery. Manual Structure The design of handwheel ensure safe, reliable, labor-saving, small volume. When it don’t have electricity, it can be manually operated by handle. If it is not easy operate by manus, you can put the wrench in the wrench folder, then you can easy to use it. Indicator Indicator installes in the center axis, so it can observes the valve position. It adopts convex mirror design, no cumulate water, more convenient to observe. Desiccator It is used for control temperature, avoid internal moisture of electric actuator condensed because of the changing of temperature and weather. Sealling Good sealing performance, and the protection class of standard product is IP67, and it can chooses IP68 protection grade. Limit switch Mechanical, electronic double limit. Mechanical limit screw is adjustable, safe and reliable; electron limit switch is controlled by the cam mechanism, easy adjustment institutions can set the position accurately and conveniently, and it doesn’t affect by excessive handwheel. Self-locking Exact worm and worm gear can efficiently transfer large torque, high efficiency, low noise (max. 50 dB), long life, and it has self-locking function to prevent the inversion, transmission part is stable and reliable, no need to add oil. Anti-off bolt When Removed the shell, the bolt would be attached to the shell and didn’t fall off. Install The installation size of the bottom conforms to the international standard ISO5211 / DIN3337, The holes are double square so that it’s easy to fix the linear or 45 ° corner valves attached square bar, adaptable. It can be installed vertically, also can be installed level. Circuitry Control circuit conforms to the single-phase or three-phase power supply standard, reasonably compact line layout, wiring terminals can effectively satisfy a variety of additional functional requirements.
