electric rotary actuatorSpecifications
It's variation in wide rage of output torque and control options fit your specific requirement.
DescriptionQ series electric actuator is specially designed for quarter turn operating applications such as Ball, Butterfly, Plug valves, Dampers and similar usages.It's variation in wide rage of output torque and control options fit your specific requirement.Q series electric actuator provides high reliability and performance for your automation plan.
FeaturesCompact and low weight due to high grade aluminum alloy for housing.High corrosion resistance due to hard anodizing on inside & outside and polyester coating on external surface.Various output torque from 50Nm to 3000NmWide range of voltage availableSelf locking with minimum backlash in the transmissionRugged construction with o-ring system giving water and explosion proof.(optional : explosion proof/Eexd IIB T4, IP68)Hand wheel for manual operation engaged by a manual / auto lever arranged for power preference.Easy mounting base standard to ISO5211Standard 4limit switches. 2 for operation, 2 for extra(dry contacts)Torque switches(except for RE-008)LED lamps on indicator monitoring valve position and operation(option)Space heater with thermostat for preventing overheat.Removable drive bushing with under hung for easy machining and tight connection.
Manual override(Declutching system)Manual/Auto lever and handwheel engagement for emergency manual operation.Power drive automatically resorted by motor start unless lever padlock to prevent it.
Cam block and limit switches4 cams and 4 limit switches arranged as block. 2 travel limit switches for operation2 auxiliary limit switches as dry contact for customer usage.Easy setting for upside by two screws for tight lockup.Each cam be set independently.Once setting is done, each cam keep up position permanently.
Terminal blockEnough number of terminal strips for customer's convenience(Max 22 points)Proven reliability and tight wiring connectionStripped length : 8-9mm / 0.33 in (2.5)Terminal dimensions : 10 x 22 x 32mm
Heater7~10W, Ceramic housing with thermostat to prevent over heat comparing with set temperature.No risk of electricity leakage.
Captive cover boltCover bolts are specially designed to prevent loosing it during maintenance or installation.All external bolts are stainless steel for rust prevention.
Indicator sustained by springDirection of Visual indicator is set by factory before delivery.In case of changing it's direction, just grip indicator plate and change the position.Spring underneath indicator plate sustains the set position unchanged.No need to loose screw and tight it again at all!
Slut on window cover for draining rainwaterRainwater inside of window cover may affect the sealing of window.To prevent this, drain slut is useful to prevent this effect.
Tapered interface between cover and housingTo take off cover from housing is not always easy when installation and maintenance as long as actuator is expression proof grade because of very small tolerance in interface between cover and housing.RE actuator has also very small tolerance in interface but tapered interface provide easy work.
Torque switchesTorque switch provided for protecting motor & internal electrical component from over heat caused by overload of valve.
Removable drive bushing with under hungDrive bushing is removable type for easy machining for stem adaption.4 Under hungs for tight and rugged connection between driving shaft and bushing.Easy mounting on valve.
Local control unit(LCU)
Type1Simple 4 step rotary switch-Remote-Local(open/stop/close) monted on bottom side of housing
Type2- Consists of two rotary switches.- One for selection of remote/local, and other one for open/stop/close.- 4 indication lamps monitoring power, open/stop/close.
Visual indicator with signal LED unit(SLU)Big size plate indicator with 4 monitoring lamps(Power, Over torque, Open and Close)
Position indication unit(Potentiometer kit, PIU)
High resolution potentiometer with precisely machined gearing directly engaged with driving shaft provides continuous monitoring of position of valve and actuator
Proportional control unit(Q-01-A)Q PCU is a combination of electronic positioned and position transmitter using Micro-processor providing extremely high reliability and performance.Auto calibration provide the most convenient to user without complicated setting in field installation.Field setting can be done by just pushing one button(auto calibration)Input signal range : 0~10VDC, 1~5VDC, 4~20mA,0~20mAOutput signal range : 4~20mA,0~10VDCAdjustable range : zero 8mA, open 16mAInput power 110V/220VAC ±10% 50/60Hz Power consumption : 4WInput resistance : 250ohm, Feedback signal : 1k~10k ohmLoad resistance : Max 750 ohmResolution : Min. 1/1000Position conversion accuracy : ±0.5~1.5%(depends on installation)
