1. Housing: Hard anodized Aluminium casting and external epoxy power coated against severe
Industrial environment.
2. Gearing: Precisely machined double worm gear C/W minimum black-lash, low noise, high output torque.
3. Self-locking: Provided by double worm gearing to keep position of valve unchanged against reverse torque form valve.
4. Motor: Specially designed and induction motor to generate high staring torque and high efficiency equipped with thermal protector to prevent damage from over heating. Insulation class F.
5. External mechanical stopper: Prevents over run of travel angle when limit switch fails.
6. Torque switches: Protect actuator from damage caused by overload from the driven valve over the whole travel, 1each for open/close.
7. Limit switches: Directly engaged with driving shaft to set accurate position of valve, supplying a dry contact signal.
8. Terminal: Spring loaded push type terminal for tight wiring connection under severe vibration.
9. Space heater: Anti-condensation.
10. Manual override: Auto/Manual switchable lever and handwheel engagement for emergency manual operation. Drive force automatically resorted by motor start, unless lever padlocked to prevent this occurring.
11. Handwheel: Manual operated, turn on-off valve directly when power off.

Electrical characteristics

1. Automatic identify Phase Sequence, Phase Failure Protection.
2. DC24VVoltage Class for remote control.
