HML Intelligent Linear Electric Actuator

HML Series Linear Electric Actuator
HML Series Linear Electric Actuator

HML Intelligent linear electric actuator provide manual automatic clutch, excellent weather resistance and shock resistance. When the actuator is powered off, the self-locking transmission mechanism ensures that the valve position remains unchanged, and an electrical limit is set to prevent overtravel.

Torque Protection

A sensor serve as overload protection for the entire valve travel, and you can setting a different torque volume between 40~120% of rated torque.

 

 

Limit Protection

Set this function is avilability, the actuator should stop automatically while the valve position reach the limit position.

 

 

Automatic Phase Ratation Correction

Actuator monitor the phases and run in the correct direction regardless of the sequence of power supply connection that is realized through a phase rotation correction Boolean logical calculation.

Without this function it may damage the valve in unconsciously.

 

 

Instantaneous Reversal Protection

The motor control logic automatically add a time delay in switching the motor when the actuator is ordered to reverse direction instantaneously,this function can preventing unnecessary wear to the valve stems and gearboxes.

 

 

Phase Failure Protection

Actuator real time monitors all three phases of the power supply during operation to prevent lose phase action. (3-phase power supply only)

 

 

Valve Jammed Protection

Electronic latching inhibits the actuato torque protection function around 5 seconds and allows the motor to generate 2 times rated torque to unseat the stuck valves while starting operation signal is enabled, if the actuator in the above-mentioned second time have no movement, control circuit will cut off the power supply of the motor to prevent the further valve damage or motor burm out.

 

 

Motor Thermal Protection

Two thermostats are embedded in the windings for provide thermal-protection by de-energised motor in the event of motor over the maximum temperature.

 

 

Electric Protection

The input and output signal channel of circuits are designed as photoelectric isolate mode.

 

 

Main Technical Characteristics

●The input voltage range:single Phase 50/60Hz:110,120,220,230,240V 3-Phase 50/60Hz:200,230,240,380,400.415.440. 460,480V

●Using the absolute encoder, the valve position never lost.The absolute encoder can ensure the high precision, zero wear, long life, strong anti-interference, no battery support.

●Optional all electronic torque detection technology to realize the torque continuous measurement, the over torque value can be adjusted without secondary calibration, it is unnecessary to consider mechanical wear.

●Perfect bus supporting plan: Profibus dp. Modbus, FF, Hart, Device Net five kind of bus available.

●Unique double speed control mechanism, can make the actuators in work process avoid causing fluid surge effect.

●Infrared setting device and knob (magnetic isolation technique) all can set working parameters, convenient and practical, truly realize free open cover.

●Perfect level 3 password protection, but to different customers or operator separate authorization, prevent fault parameters set to actuator fault phenomenon.

●Provide five field programmable non-hold type relay feedback, provide an alarm non-hold type relay feedback, extensible four hold-type relay feedback.

●Input /output signal channel have been photoelectric isolation (can bear 2000 V surge voltage).

●Operating temperature range: -30C -+70 C.

●Use humidity range or less 90% RH, non-condensing around, do not contain strongcorrosive, fammable and explosive gas or dust.

Testing For All Actuators

All actuators manufactured by HEARKEN are individually tested. Testing is carried out to check the leakage in both internal and external. The angle of rotation and Torque values. All bodies are stamped with year, month of production, size and serial number.
