Electric Actuator
Electric actuators, also known as electric actuators. It is a drive that can provide linear or rotary motion. It uses some kind of driving energy and works under some kind of control signal.
Powerful functions: intelligent, proportional, switch and various signal output types
Small size: the volume is only about 35% of similar products.
Lightweight and comfortable: the weight is only about 30% of similar products.
Beautiful and generous: aluminum alloy die-casting shell, delicate and smooth, can reduce electromagnetic interference.
Precise and wear-resistant: the output shaft of the worm gear is forged with special aluminum alloy, which has high strength and good wear resistance
Easy to use: no refueling, no spot checks, waterproof and rust-proof, and can be installed at any angle.
Anti-corrosion and rust-proof: brackets, couplings and screws are all made of stainless steel.
Industrial Grade Actuator
①Compact structure, large output torque
②Self-locking gear train can maintain the valve position when the actuator is de-energized
③Very good vibration resistance
④ Very simple setup - no specific tools required
⑤Adjustable mechanical stroke limiter to prevent overtravel
⑥Detachable drive sleeve for easy processing
⑦ All actuators are equipped with emergency handwheel and mechanical position indicator as standard
Main features
Transmission gear
• The gear transmission system consists of 2 reduction stages: the first stage is directly driven by the pinion on the motor drive shaft, which is a planetary system. The second stage, driven by the satellite wheels of the planetary gears, consists of a worm gear and a worm gear.
Emergency handwheel
• In case of power interruption or failure of the control system, the presence of a handwheel allows the operator to easily manually drive the valve to any desired position.
Asynchronous motor
• Asynchronous motor technology provides the highest ratio of starting torque to nominal torque. Therefore, the maximum torque capability of the actuator is available to unseat the valve from the beginning of the stroke.
Removable drive bushing • The output drive sleeve can be easily removed from the actuator without the use of any special tools to accommodate the valve shaft.
Positioning operation for the switcher
• Weatherproof design
As standard, our actuators are protected by IP67 (NEMA 4) weatherproof enclosures in accordance with CEI 144 recommendations. Higher levels of protection are available on request (please consult us).
• Corrosion-resistant design
Our actuators can also be configured to operate in harsh environmental conditions such as: Industrial corrosive atmospheres (chemical, alumina plants, ie) Marine corrosive atmospheres (onshore and offshore)
Simple and convenient mechanical operation
Multi-turn Actuator ST Series
Extensive control options
Standard controls (no integrated controls Customer provides control logic to process all data received from actuator electrical contacts
Power reversing starter installed in customer's own cabinet. INTEGRAL+ control (A115)
The INTEGRAL+ control system is fully configurable and can perform all actuator control functions including generating status reports, fault handling, protection systems and command processing.
It provides local control that can be disabled locally or from a remote location.
Reversing starter integrated in control unit POSIGAM+ control
The POSIGAM+ control (the third type of actuator) is based on the same electronic platform, but includes a positioning function.
Proportional signals are used to control the actual valve position (feedback) as INTEGRAL+ actuators (setpoint) and signals.
