IOC straight stroke old actuator

In case of power failure, the hand wheel can be directly driven by the low-speed lock type manual/automatic clutch (or the independent gear driven hand wheel is used on larger models) to switch the actuator. If the switch lever is in the automatic position. The electric drive is an effective drive. In the manual position, the manual drive is effective. In case of emergency, press the switch lever down to the "Manual" position. Avoid the occurrence of obstacle release. Manual operation has the effect of air stroke "hammering", which is conducive to easy operation of the valve.

Phase failure protection
The actuator has perfect power supply phase loss protection function. Always check that the motor is stationary. The power supply is out of phase during operation, so as to avoid motor out of phase operation or even overheating and burning, and the power supply out of phase information is displayed on the display screen.
Motor protection when valve is stuck
The torque protection function is temporarily disabled within 5〜10 seconds after the excitation motor signal is sent. The actuator will provide a torque of 1.2〜1.8 times of the rated value to the "stuck" valve, so as to realize the valve unclamping. If the actuator does not act within 5〜10 seconds, the control circuit will cut off the power supply of the motor. Avoid valve damage or motor burning
