Electric Part-turn Actuators – Type SG
The Type SG (SG NORM) is the base actuator from which a variety of part-turn actuators are designed. SG actuators are typically used in the automation of quarter turn valves. Due to the modular design principle it can be combined with various controls, from simple open-close control to explosion proof version or micro controlled version. The controls are connected to the actuator via a simple plug/socket connection.
The basic NORM actuator consists of a motor, worming gear, control unit, hand wheel for emergency operation, electrical connection and valve attachment. Torque values can be increase with the addition of gearboxes in order to automate valves of various sizes and pressures within any plant.
