Tipo de trabajo

Modulación

The actuator read the target position value from control system through 4-20mA, 2-10V or field bus such as modbus, ethernet and etc.

Then actuator drive the valve to the target position with interior control algorithm.

The actuator will always output the real-time valve position through 4-20mA, 2-10V or field bus.

Operated in type of duty S4, the actuator can starts 1200 times per hour.

Features

Fully Capsulated Control Unit

The control unit is fully encapsulated with polyurethane. This greatly enhanced proof performance against moisture, condensation, salt and vibration. So it is applicable in harsh environments such as high humidity, dust, strong temperature changing, vibration, etc.

With 6kV EFT and surge protection circuit, the stable control to the valve can be ensured even in worst electromagnetic environment.

By self-adjustment algorithm, the actuator can keep the precision against different loads conditions and mechanical wear by time.

Easy-to-use Limit Switch

With DCL’s patented limit switch design, the actuator’s end position of open and close can be easily configured only with a hexagonal wrench.

In the meantime the micro adjustment feature of limit switch can improve the precision when setting the end-position.

Patent No. ZL 201020214725.8

Motor with Over Temperature Protection

DCL specially design the motor to fit the actuator requirement so that the motor in DCL actuator can supply a high start torque while maintain a high efficiency in the start phase to make the temperature rise as low as possible. In the meantime the motor have a small moment of inertia to make sure the high precision in modulation.

There is an over temperature protection device mounted in the motor which will cut the power supply when the motor temperature goes higher then the limited temperature(105℃/85℃ can be selected up on the application scenario) and connect the power supply again when the temperature recovered below the Normal temperature.

Dual Position Limiter

There are 2 position limit devices to protect valve from damage by operation over swing angle.

Electric limit switch are mounted on the both end-position of OPEN and CLOSE. So the power supply to motor will be cut off to stop driving the valve after limited end-position was reached.

Also there are 2 mechanical limiters mounted on the output shaft to protect the valve from swing over stroke range. The mechanical limiter will not take effect in normal operation cause the electric limit switch is ahead of the mechanical limiter and will be triggered before the output shaft can reach the mechanical limited positon.

Opciones adicionales

Over-torque Protection

When the valve is stuck by some reason such as solid impurities in the liquid or malfunction on some mechanical parts, the torque on output shaft of actuator will increased sharply beyond the limit torque value when driving the valve, then the actuator would trig an over torque protection to stop driving the valve in order to protect the valve from damage.

Dehumidifying

You can choose a dehumidifying option on DCL actuator. Then a electric PTC heater will be mounted in the actuator to reduce humidity to protect circuit from malfunction in high range of temperature changing circumstance due to condensation.

The PTC heater will be in working mode as long as power is supplied to actuator.
