Besides the intelligent series, YEPEF (Yangzhou Electric Power Equipment Manufacture Co., Ltd.) keeps two classic lines: ordinary multi-turn and ordinary quarter-turn valve electric actuators. Mature and rugged, they are the conventional choice for power-plant and general industrial valve duty.
Ordinary multi-turn actuators output multiple revolutions for linear-lift valves such as gates and globes: the motor drives the stem nut through gearing, turning rotation into stem travel. Ordinary quarter-turn actuators output a 90° stroke for butterfly and ball valves, usually built as a multi-turn base plus a secondary worm-gear reducer.
The core setting work is the same for both: travel (limit) and torque cut-offs — travel defines where open and close are, torque protection stops the unit when it cannot reach position. Set travel first, then torque, with torque set at the travel end positions; "ordinary" products still demand full setting discipline.
YEPEF's ordinary actuators are known among power-plant users as rugged and easy to commission. For selection and quotation, feel free to contact us.
