1. Housing: Hard anodized Aluminium casting and external epoxy power coated against severe
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.
1. Automatic identify Phase Sequence, Phase Failure Protection.
2. DC24VVoltage Class for remote control.
3. Convenient and flexible for wiring way.
4. Impenetrable design to improve the sealing of actuator for local button box.
5. Five pieces dry contact signal indicate the sealing of actuators, conveniently monitor DCS system.
6. Setting monitoring relay, supplying comprehensive fault signal for DCS system.
7. For turn button, can sue common padlock locking according to requirements to prevent the false operation.
