Type of Duty
Modulating
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.
On - Off
The actuator read the open or close requirement from control system through IO interface such as passive signal or 24VDC/220VAC active signal.
Then actuator drive the valve to the end-position of OPEN or CLOSE as input signal required.
The actuator will output a feedback signal of OPEN or CLOSE when end-position been reached.
Operated in type of duty S2, the actuator can drive valve continuously for 15 minutes.
Features
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.
