1. Power supply: three-phase four-wire, 380V, 50Hz (special orders can be 415V, 660V, etc., frequency can be 60Hz)
2. Working environment: (If it is explosion-proof, please refer to the instructions of the first-level electric actuator)
2.1 Ambient temperature: -20C-60C
2.2 Ambient relative humidity: Less than or equal to 90% (at 25C)
2.3 The working environment does not contain corrosive, flammable, and explosive media;
2.4 Protection level IP67
3. Short-time work system, the time is 10 mins;
1. If the fully open and fully closed positions of the valve are controlled by the stroke mechanism or the torque mechanism, the mechanical limit must be loosened before adjusting the stroke or torque.
2. If the fully open and fully closed positions of the valve are controlled by the mechanical limit and the torque mechanism sends a signal, the adjustment method is as follows: Manually operate the electric device to put the valve in the predetermined position; Adjust the corresponding mechanical limit (striker pin) so that it just hits the output shaft, and tighten the locking nut and cap nut of the striker pin; Adjust the torque mechanism and gradually increase the output torque value until the valve can be turned into place.
The rgearbox converts the output power of the high-speed, low-torque motor into the power of the output shaft of the low-speed, high-torque actuator. The manual switch is semi-automatic, that is, when it is manual, move it in the direction of the arrow on the switch handle, and it will automatically reset when it is electric.
