General Metso Automation is a leading designer and provider of Valvcon compact, reliable, electronically controlled electric actuators for valves and dampers. Metso Automation offers a complete line of electric actuators for accurate positioning of dampers and valves in the aerospace, automotive, consumer services, discrete manufacturing, energy, environmental, oil/pipeline, petrochemical, power/utilities, process, recreation, transportation, and water/wastewater industries. Metso Automation has developed and introduced the industry's most innovative Valvcon electric actuator products, including simple "set and go" calibration, intelligent processor-based digital electronics,"Plug-in" accessory boards, Back-Up Power actuators, as well as electric actuators designed for remote control, solar-powered applications and two-wire network applications. Metso Automation has built its reputation and success on the ability to envision,implement,and deliver innovative Valvcon actuator technology products and services to support emerging market requirements. As emerging technologies and market needs continue to evolve, Metso Automation will lead the way with high quality Valvcon electric actuators that exceed industry expectations and further refine the valve actuation process. Features and Benefits Motor The motor will be capable of running continuously at full torque for up to 15 minutes at ambient temperatures at or below 104 degrees F. Subsequently, the motor must be capable of 75% duty cycle. Motors will be split phase, capacitor driven with an auto reset thermal sensor, and will provide high starting torque and be totally enclosed within the actuator's housing cover. Lubrication All rotating power train components will be coated with a multi-purpose grease. Lubricants will be suitable for ambient conditions of -40° F to 150° F. For operation in temperatures between 32° F and -40° F an optional heater and thermostat assembly must be included. Gearing The powertrain will be comprised of hardened steel, machine cut spur gears. Non-metallic, aluminum, cast or stamped gearing will not be permitted. Manual Operation A wrench-operated override shaft will be provided for manual operation. As an option, a metallic hand wheel may also be provided. The override device will be engaged through a declutching mechanism,which separates the final output drive from the motor output.		> C Q) «■* O

	Limit Switches Actuators will have two standard end of travel switches, single pole double throw, rated at 15 amps at 250 VAC. The limit switches will be activated by metal cams mounted on the actuator drive shaft. At the end of travel, the power will be routed through the limit switches to a terminal strip location for pilot or position indication applications. The limit indicator outputs will be fuse protected with auto-resetting polyfuses, with a working limit of 0.25 amps, to protect the limit switches and internal circuitry from possible overloads originating outside of the actuator.To simplify maintenance, these polyfuses will be permanent and do not need to be replaced.They reset automatically, shortly after the overload condition is corrected — in approximately 3 minutes.Two additional limit switches may be added to the actuator, adjustable to operate at any position,as required by the process application. Open/Close Operation Open/Close actuators will be controlled via two, powered, maintained contacts, one for driving in the clockwise direction, and one for driving in the counter-clockwise direction. Power may be removed mid-stroke to position the valve. The AC input power will be fuse protected on both AC Hot and AC Common. The fuses will never blow in normal operation — they will be conservatively rated and soldered in place for high reliability. Proportional Control (Modulating Operation) Modulating control actuators will accept a variable, proportional 4-20 mA or 0-10VDC valve position signal and respond by positioning the valve linearly with an accuracy of 1%. Normally, the actuator will drive clockwise in response to a decreasing control signal; however, the actuator will be capable of "reverse acting" operation (driving counter-clockwise in response to a decreasing control signal) with no necessitated internal wiring changes. The actuator will also supply a 4-20 mA or 0-10VDC position feedback signal, and provide the ability to adjust the cycle time of the actuator. A slide switch will enable the user to set the actuator response to a loss of control signal. Locked rotor protection will detect whenever the actuator is unable to achieve the position commanded by the control signal, and will terminate power to the motor in order to prevent damage due to repeated stall conditions.
