QT ELECTRIC VALVE ACTUATOR
QT series power-off reset electric valve actuator is used to control valves with a rotation of 0°-90° and other similar products, such as butterfly valves, ball valves, dampers, plug valves, louver valves, etc. It uses AC110V, 220V, 380V AC power supply and DC24V DC power supply as the driving power supply. The actuator has its own power supply. It can be widely used in petroleum, chemical industry, electricity, metallurgy, pharmaceutical, papermaking energy, water treatment, shipbuilding, textile, food processing, building automation and other fields. At thesame time, it has many advantages such as small size, light weight, exquisite appearance, unique structure compactness, quick opening and closing, easy installation, small operating torgue, convenient operation, digital display of valve position, no maintenance required, safe and convenient use, etc.

PROEDUCT STRUCTURE
DESIGN FEATURES AND MAIN FUNCTIONS
Shell
Hard anodized die-cast aluminum shell, external epoxy powder uncoated, suitable for harsh working environment.
Input voltage range
Three-phase: AC340V~420V 50/60HZ Single-phase: AC220V~240V 50/60HZ
Features
The microcomputer control board collects proportional signal input internally, and the output command signal is processed to directly drive the motor to realize the opening and closing of the actuator, and provides proportional signal feedback, proportional signal control, and multi-channel field programmable relay output.
Control type
Control signals are divided into on-off type and modulating type, power supply is divided into on-off type and modulating type, and power supply is single-phase and three-phase. The on-off type only accepts the switch signal provided by the external, which is processed by the microcomputer control board. The output command is amplified and directly drives the actuator motor to perform remote opening and closing actions. The modulating type can receive the proportional signal provided by the external on the basis of the on-off type
Ambient temperature
Working temperature range. ≤90%RH, no condensation, -25C~+60C (special temperature needs to be customized),
Protection grade IP68, explosion-proof level ExdII CT4GB
Working duty: short-term 10 minutes
