Installation, Operation and Maintenance Manual
3 GENERAL INFORMATION AND FEATURES
3.1 General Information
HQ-005 electric actuators are designed for the operation of small size quarter turn valves; e.g. ball, butterfly and
damper valves etc. with high reliability and efficiency.
3.1.1 Performance
Rated Current (A) 60/50 Hz
95V ~ 265V AC
or
24V DC/AC
3.1.2 Standard Technical Data
3.1.3 Optional Technical Data (Optional)
3.1.4 Duty Cycle
1)
Duty cycle rated IEC60034 – S4 70%
Exceeding the actuator’s rated duty cycle may cause thermal overload.
Note:
1)

High grade aluminum alloy, corrosion resistant coated
110 / 220V AC 1 Ph 60/50Hz
24 V DC/AC
S4 70% / S2 30min (IEC 60034)
2 x open/close SPDT, 250V AC 5A rating
2 x open/close SPDT, 250V AC 5A rating
Continuous position indicator & full position LED lamp
Torque overload indicator via flashing LED indication
Potentiometer Unit (0~1KΩ)
Proportional Control Unit (input, output 0~10V DC, 4~20mA DC)
Current Position Transmitter (output 4~20mA DC) , 0~10V
The operation time at a constant load is short,
so that thermal equilibrium is not reached.
The pause is long enough for the machine to
cool down to ambient temperature. The
duration of the short –time operation is limited
to 15min (10min, 30min)
The duty is a sequence of identical cycles
which consist of starting time, operation time
with constant load and rest period. The rest
period allows the machine to cool down so
that thermal equilibrium is not reached. The
relative on-time at S4-25% or S4-50% is
limited to 25% and 70% respectively.
