Heavy Duty Electric Multi Turn Actuators By Remote Control Status Protection
Overview
The multi-turn electric actuator is easy to debug and uses the infrared setting tool for simple, safe and fast non-intrusive adjustment. Use the Setup Tool Professional Edition to enter and adjust actuator settings such as torque limit, control and display functions. Provided with a unique intrinsically safe setting tool, the actuator can be non-intrusively set in any environment, regardless of the power supply.
Multi-turn electric actuator for control and regulating valves, its switch-type products are suitable for applications with up to 60 starts per hour, the regulated products are suitable for applications with up to 1200 starts/hour, and thanks to the addition of intelligent control Units make it more accurate and more accurate.
Features
1, manual operation
Direct drive handwheels (or larger models and geared handwheels used on AKM) provide reliable emergency manual operation in the event of a power failure. The padlock manual/automatic clutch ensures safe operation even when the motor is running.
Note: Motor operation is always preferred unless the manual/automatic handle is intentionally locked in the manual position. Both the direct drive and the independent gear driven handwheel have a free-range "hammering" effect.
2, non-intrusive settings
All actuator settings and diagnostics are performed through a sealed indication window, eliminating the need to remove the cover on site and expose the internal control mechanism.
3. Local control
Field control switches and padlock-type field/stop/remote selection operate the internal magnetic reed switch, eliminating the need for a through-shaft that seals against moisture.
4, position control
The Hall-effect magnetic pulse system accurately measures and controls the travel of the actuator without the use of any gears and switches.
5, the terminal box
The individually sealed terminal box ensures the integrity of the motorized seal even when the terminal box cover is opened for field wiring.
6, AKC / AKM electric and drive
The motor shaft and the worm are independent of each other for quick replacement. The low inertia, high torque motor allows the peak torque to be reached quickly after the motor is started, and there is almost no overrun during non-excitation. The temperature coil has a precise temperature sensor that is unaffected by the ambient temperature and allows the motor to be in optimum heat capacity. The motorized section includes a free-range "hammer" device that helps to open and close the over-tightened valve. The worm gear and the worm are individually immersed in the lubricating oil to suit the maximum ambient temperature difference.
7, flexible drive connection
Cast iron, water sealed housing. A simple, detachable drive bushing can be machined to the valve stem for connection to the valve.
