Feature

Compact Lightweight Industrial Anti-vibration/Waterproof High Torque 90 Degree Rotary Electric Actuator for Ball Valves

1. Exquisite design,excellent performance, light weight and big output torque.

2. The inside and outside of closure is treatedby hard oxygen, while epoxy resin + powder spraying are adopted for external treatment,which posses good antiseptic performance.

3. Protective grade of product is upward of IP67.

4. Connection dimension of output end is in accordance with the National Standard ISO5211.

5. Connection shaft sleeve can be replaced, and easily processed and installed.

6. Double worm wheels structure, which has self-locking function, and is of external adjustable mechanical limit.

7. Power-driven/manual operation mode canbe changed easily through hand shank, then automatic reset to electronic control after power on.

8. Built-in torque switch,and carry out overload protection on electric actuator. Moreover, it embedded thermal protector to carry out dual-protection on electrical machine. Indicate the valve position continuously by big window for better viewing.

9. Multiple filed control unit,provide the best performance according to the requirement of users. Intelligent control unit could be selected.
