Eldon – ITQ 010-300
Self locking – Provided by double worm gearing to keep position of valve unchanged against reverse torque from valve.
Motor – Specially designed induction motor to generate high starting torque and high efficiency equipped with thermal protector to prevent damage from over heating.
Torque switches – Protects actuator from damage caused by overload from the driven valve over the whole travel. 1 for each open/close.
Manual override – Auto / Manual switchable lever and hand wheel engagement for emergency manual operation. Drive force automatically resorted by motor start, unless lever padlocked to prevent this occuring.
External mechanical stopper – Prevents over run of travel angle when limit switch fails.
Removable drive bushing and ISO5211 mounting base – (F07~F16) for easy mounting on valve.
