Product Description

 

Quarter-turn electric actuator can be used to control various valves with a regulating angle of 0-90° and the torque range is: 35-10000Nm. It can used for control all of quarter-turn valve like: flue cut-off gate, boiler's primary and secondary wind, boiler's side wind, air pre-heater inlet and outlet damper regulator, butterfly valve, ball valve, louver valve, damper, plug valve, flapper valve, etc.
Explosion-proof Grade: IP67, IP68.


Advantage:

 LED display:
It has a dot-matrix liquid crystal display with high resolution. The opening size of the valve is displayed timely in large numbers and operation menu . It can display alarm information and working state timely in Chinese according to working condition. The high light LED luminotron will indicate the open or close limited position of the valve.

Adjustment without opening the cover:
Working parameter setting and system condition check can all completed through operation button or infrared setting indicator. As it is unnecessary to open the electrical cover, the dust, moisture and other harmful materials in the air cannot enter the interior of the actuator, enhancing the reliability of the electrical control part greatly.
 Dead band adaption automatically:
Under the 'remote automation control' mode, system will measure location precision automatically and define optimum dead band figure based on the operating condition, to ensure the actuator function with high location precision and no vibration.
 Convenient and quick wire connection:
The wire connection of the actuator adopts fast connection mode. The outside wire connects to the plug so pulling out the plug will disassemble the actuator. The plug is waterproof so that error occurred by reconnecting wires in the process of maintenance is avoided.
 Absolute code position sensor:
The intelligent linear electric actuator of our company can choose and distribute absolute code position sensor. The sensor adopts contactless measurement. It has superb measurement precision and extra-long working life.
 No information lost in condition indication when power out:
The configurable bistable relay output contacts can indicate various conditions of the valve, including switch limit, over torque, operation indication and position of the valve, etc. it will remain in output state even when power out.

 Multiple control methods:
1.Control on site
Choose the 'control on site' mode by 'on site' button. You can use open button, close button or infrared setting indicator to control the valve to open, close or stop.
2.Distant switching volume control (also called distant manual control):
Switching volume control has three input ends: open valve, close valve and stop/remain. On-off control can realize 'remain' or 'inching' mode control through outside wires connections.
3.Distant current control(also called distant automatic control):
User can control the function of the actuator through DC4~20mA current in order to locate the valve precisely.
4.Two lines control:
The actuator has the function of two lines control. It can realize the special control situation "open when there is signal, close when there is no signal".

Thorough protection function
1.Motor overload protection:
When motor stalls in actuator operation process, control system will stop motor rotating immediately. This function not only protects the valve, but also protects the actuator itself.
2.Valve position limit protection:
When the actuator moves to the open position or close position, it will stop moving automatically.
3.Instant reverse protection:
When the actuator receives an order to move to the opposite direction, it will add a time delay automatically to avoid unnecessary wear of the valve shaft and gearbox.
4.Motor overheating protection:
There is a thermorelay in the end of the motor winding to check directly the temperature of motor winding. The control circuit will forbid actuator operation when thermorelay finds motor winding over heating.
5. Electric isolation protection:
The input and output channels of the actuator all adopt Electric isolation protection, which ensures the reliable work of the actuator without interference.
electric braking function:
The actuator has electric braking function which largely improves the location precision of the valve.
efficient low noise:
It has an accurate retarding mechanism with small interval, high efficiency, low noise (50 db at most), long operating life.

  

Wide choice of controls

You can opt for integrated control or remote control station to meet the requirements of your particular system and the environment in which the actuators are to be used.

Standard control 

Standard control (without integrated controls) The customer provides the control logic to handle all the data received from the actuator electric contacts. The power reversing starters are housed in the customer's own cabinet. 

INTEGRAL+ control

The INTEGRAL+ control system is fully configurable and can perform all actuator control functions, including production of status reports, fault handling, protection systems and command processing. It offers local controls which can be disabled either locally or from a remote location. The reversing starters are incorporated in the control unit. More information in our INTEGRAL+ catalogue (A115)

POSIGAM+ control

The POSIGAM+ control (Class III actuators) is based on the same electronics platform as the INTEGRAL+ but includes a positioner  function. Proportional signals are used to control of the actuator  

(setpoint) and to signal the valve actual position (feedback).
 

1- Valve Position Limitation and Protection
Actuator automatically stops after traveling to the closing position or open position.
2- Protection of Instant Reverse Running
When the actuator receives a command for motion in the opposite direction, it automaticaly add a time lag, to prevent unnecessary wear to the valve shaft and transmission box.
3- Power Brake
It helps to improve precision of valve position
4- Access-free Debugging
Working parameter setup, system status inquiry can be realized on buttons or infrared controller, without needs to open the electrical protection cover, so that dust, moist and other hazardous substances in the environment can not enter the actuator and the reliability of electrical control will be greatly improved
5- Dead Zone Self-adaption
In "Remote Auto Control" mode, no setting or dead adjustment will be required, and the system can. on basisof its operating status. automatically measure and locate and precisely determine the dead zone values, ensurind vibration-free and high-precision operation of the actuator
6- Easy Wiring
Quick-set connection is adopted on the actuator for wiring. The external wire is connected to the plua, and the actuator can be removed simply by unplugging operations. The plugs are water-proof and thus prevent errors by reconnection during maintenance process.
7- Power-loss-safe Status Indication
The configurable bi-stable relay output contact can be used to indicate various status of the valve (including open/close limits, over-torque, operating indication or destination position of valve, etc.), which will not change even the system loses power supply. 
8- Multiple Controls
1) Field control
When the system runs in "Field Control" mode by usina the "Field Control" button, the "Open" "Closetbuttons or "Infrared controller" may be used on site to control the opening, closing or stopping of valve.
2) Remote switch control
The switch control provides three input terminals, respectively Open, Close, Stop/Hold: Switch control can realize "Hold" or "Inch" control by external circuits.
3)Remote current control (also known as Remote Auto Control)Users can control the actuator operation by DC4-20mA electric current, to realize precision positioning of valve.
4) Two-wire contro
