  Summary


LQ-SR electric actuator with spring return is a quarter-turn actuator equipped with a mechanical spring module to achieve safe fail. When the power supply is normal, the spring mold stores energy. When the power is off, the spring releases the stored energy to drive the actuator, so that the valve returns to the preset safe position(fully open or fully closed). The reset speed is accurately controlled, and the reset process is safe and stable to prevent pipeline fluid leakage or cause environmental explosions.

LQ-SR series electric actuators with spring return can be equipped with an external clutch type manual control device. Theactuator can be manually operated to move the valve to the locked position by the manual control device. After power on, it will be automatically unlocked.
