	Feature ＊Housing for oil hydraulic valve are clear and visible and so,it is very easy observation of inner moving. ＊　Tranceparent oil hydraulic valve are not model bat actuate,same as moving function as actual valve. ＊　Moving of valve each other,are actuated by circuit control,it is very hard to understand in total by the study of text book and or the model cutting section-non moved individual.On the our side ,very easy study to learn valve construction,function steo by step moving by circuit control without any disturbance.
＠　全員参加の実習 Basic study by the oil hydraulic experimental equipment are consist of practive circuit and characterstic test,it will be able to study both,at once,easy,and also saving long time study on the desk. ＠　Will be able to operate by personal computer Available to operate by combined personal computer for the subject of pump on,off and cylinder moving etc.,
