Quarter-turn Electric Actuator
Quarter-turn actuators are used to operate ball valve, plug valve or butterfly valve, damper valve, louver valve and any quarter-turn or part-turn device like: flue cut-off gate, boiler, primary and secondary wind, boiler's side wind, air preheater inlet and outlet damper regulator, etc.Protection Grade:lP67.
Industrial grade actuator
Carefully designed, scientific design structure
Product Features
Compact structure, large output torque
Self-locking gear train maintains valve position when actuator is de-energized
Very good vibration resistance
Very easy setup - no specific tools required Adjustable mechanical travel stop to prevent overtravel
Removable drive sleeve for easy machining
All actuators come standard with emergency handwheel and mechanical position indicator
Special design
• 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)
Many good reviews

Main features
Mechanical end stop
• Electric actuators are equipped with adjustable mechanical stops to prevent possible overtravel during manual operation.
Position indicator.
•Visual position indicator can clearly indicate the current valve position. Infact, this indicator is mechanically connected to the valve shaft.
Travel limit switch
• Thanks to the cam block system, travel limit switch adjustment can be done with only a standard screwdriver. No special tools are required.
• Each cam can be set independently of the others.
•The cams are automatically locked in their respective positions, and once adjusted, are not affected by vibration.
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.
Motor thermal protection
•Built-in motor temperature switch can prevent the motor from overheating.
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.
Lubricating
• Gears are designed to ensure a lifetime of grease lubrication, which greatly reduces the need for periodic maintenance
Extensive control options
Standard controls
The customer provides the control logic to process all data received from the actuator electrical contacts. The mains reversing starter is installed in the customer's own cabinet.
Integral control
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. The reversing starter is integrated in the control unit.
Positioning control
The positioning control is based on the same electronic platform, but includes a positioning function. Proportional signals are used to control the actuator (setpoint) and signal the actual position of the valve (feedback).
