摘要： There is provided a multi-turn hydraulic actuator used to open/close a passageway in ground and sea industries including general industrial machines, oil refineries and chemical plants and power generating plants, among others, and more particularly, a multi-turn hydraulic actuator comprising: a hydraulic motor and a decelerator, among others, whereby high torque is efficiently obtained by using low electric power, compared to a conventional electric actuator, and whereby an operation part and a drive part are freely attached to/detached from at a user's necessity.In the multi-turn hydraulic actuator, the hydraulic motor is driven by using hydraulic pressure generated by a hydraulic pressure generator, a rotational force of the hydraulic motor is transmitted to a worm shaft of the decelerator directly connected to the hydraulic motor so that a driving shaft is rotated in a reduced speed, and the rotation of the worm shaft is selectively manually operated by setting a manual mode switch and using a manual handle.

摘要： There is provided an apparatus for measuring a position of a linear type valve which is open/shut by operation of a hydraulic cylinder. More particularly, the apparatus more accurately measures a valve position by outputting a rotation angle of a rotation sleeve which rotates by being operatively connected to a hydraulic cylinder which moves linearly, and by calculating a vertical movement distance of a valve gate which changes in proportion to the rotation angle. Further, since the structure of the apparatus is very simple, the cost of production is significantly reduced. In addition, for use, the apparatus is installed on the hydraulic cylinder by a simple method.
