Feature:
Enclosure:
IP67、NEMA 4X：Water-proof and dust-proof enclosure.
Material：Dry powder coating aluminum alloy.
Position Indicator :
All models are equipped with continuous mechanical position indicator. The external stem visual position indicator provides easily read and instantly available stem position.
Modulating Controller :
Actuator can be operated according to input signal and provide the output signal for feedback.
Input signal：4-20mA, 1-5V or 2-10V.
Output signal：4-20mA or 2-10V.
Adjustable Stroke :
Allow users to adjust actuator’s stroke to match valve stem’s stroke. (Refer to the specifications for stroke range)
Motor :
All models are equipped with DC motor and provide low power consumption, high duty cycle and efficiency.(1500 starts per hour)
Working Conditions :
Ambient temperature：-30℃ to +65℃ / -22℉ to +149℉
The humidity：30％ to 95％
Over-thrust Protection :
If the output thrust of the drive exceeds of the drive rating, the actuator will shut off by two-step control. The two-step control is as follows:
First step : If the output thrust of the drive exceeds the rating, power supply will be turned off by limit switches.
Second step : If the limit switches fail, power supply will be turned off by electronic detector. (The function only applies to modulating controller actuator)
Slow-speed operation :
Besides the standard operating speed, if slower operating speed is needed, please contact with our sales person.
