摘要： A gate valve actuator including a stem that is movable linearly in an actuator housing connectable to the gate valve. The stem acts on the gate valve to shift the gate valve between open and closed positions, respectively. The stem is driven by a motor in a first direction into a steady state operation position. In the position the stem is biased in a second opposite direction towards a shutdown position by a spring member acting on the stem. A trigger mechanism is arranged for holding the spring member in a compressed state. The trigger mechanism includes an electrically controllable trigger that is arranged for release of the spring member in result of de-energizing the electrically controlled trigger. A method for shifting a gate valve between a steady state operation mode and a shutdown mode utilizing the gate valve actuator.

摘要： An electrically operated valve actuator effective for shifting a valve (10) between open and closed positions is disclosed, the valve actuator comprising a movable member in the form of a valve stem (21) connected to a valve body (14), the movable member being driven by an electric motor (22) in linear motion between valve closing and valve opening positions, wherein electrical power to the motor is supplied via a current (25) control including a supplied current detection device. The movable member is designed for an idling length of travel (L) in the opening and closing directions during which the valve (10) is either fully open or fully closed, and the movable member is associated with buffer means (30) that during the idling length of travel gradually increases the torque and power required to move the movable member further in the open and closed positions of the valve (10), respectively.
