Page 9: Function
Type 2933, 2934, 2935, 2973, 2974, 2975 Product description Function 5.3.1.2 Actuator DN15 to DN50 By manually overriding the handwheel, the force is transmitted via a spindle and the valve is opened or closed. The medium in the valve body is either approved or blocked off. Turning the handwheel anticlockwise opens the valve, turning it clockwise closes it. To protect the actuator, we recommend not closing the actuator with more force than is required to close the valve tightly. -
