Torque 60nm to 3000nm Quarter-Turn Electric Actuator

Applicable
Adapted to the 90 ° Rotation of the ball valve, butterfly valve, damper baffle and other suitable 90 ° Rotation of the equipment to meet a variety of industrial automation control piping requirements. It can be widely used in power plant power plants, petroleum, chemical, metallurgy, power plant desulfurization, water treatment, paper making, shipbuilding, building automation and other industries. EQS series electric actuator torque range from 60Nm to 3000Nm, within this range there are a variety of models to choose from.

Features at a glance
Housing: Anodized aluminum enclosure via stearin and polyester powder coated, light weight, has a strong anti-corrosion ability. Protection class IP67 (Namur4 & 6), otherwise protection class IP68 products to choose from. Can be applied to a variety of harsh environmental conditions.
Motor: Specially designed squirrel cage induction motor starting torque to start quickly after complaining peak, built-in overheat, overload protection. With output high efficiency, high accuracy, low noise, small size and other characteristics.
PCU: The integration of high-performance microprocessors, at the installation site without complex settings, a key auto-calibration and self-calibration function to provide a good user installation convenience.
Seal: Double O-ring seal in order to achieve bi-directional sealing.
Hand operated institutions: Manual clutch lever can be pulled to achieve manually, automatically reset after power clutch can be electrically controlled functions. In addition, the hand wheel size is based on the torque required to turn the actuator design, easy, fast and convenient opening actuators.
Gears and self-locking device: When powered down, the worm gear lever mechanism and two double reduction gearbox, to prevent the valve caused due to instantaneous reversing valve position imprecise, can prevent the reversal valve position and ensure accurate and reliable. Also has a high output efficiency, low noise characteristics.
Limit switch: Limit switch, high precision, can be used to facilitate the adjustment of the angular position of the valve limit switch. When the valve is provided when excessive torque overload protection and the protection of the angular position of the switch, protect the valve and actuator.
Anti-condensation heater: Temperature 20 ± 3 when the switch is closed, to prevent moisture condensation inside. Temperature at 30 ± 3 when the switch is turned off, the temperature is too high off automatically.
Limit Bolts: Limit the two bolts from the position of the double switch actuator stroke limit in order to prevent the actuator from the worm inside.
Indicator: The indicator over a large window, a distant operator can observe the exact valve open position.
Terminal block: Plug and Play installation terminal block profile, and convenient. Spring-loaded terminals make wiring more firmly, you can shake the larger environment.
Wiring: Internal wiring introduction, crisp, easy to install.
Connection sleeve: Connecting sleeve can be removed freely processing, installation base line with ISO5211 standards, convenient and simple connection with the valve.
Lubrication: All gears and shafts are used CIATM221 lubrication, lubrication and maintenance free within five years.
Magnetic interference: Effectively prevent the interference of external magnetic field on the circuit to ensure stable and reliable electric actuators work.
