按比例阀控制方式分类是指按照比例阀的先导控制阀中的电气一机械转换方式来分类，其电控制部分有比例电磁铁、力矩马达、直流伺服电动机等多种形式。（1）电磁式电磁式是指采用比例电磁铁作为电气一机械转换元件的比例阀，比例电磁铁将输入的电流信号转换成力、位移机械信号输出．进而控制压力、流量及方向等参数。（2）电动式电动式是指采用直流伺服电动机作为电气一机械转换元件的比例阀，直流伺服电动机将输入的电信号．转换成旋转运动转速，再经丝杆螺母、齿轮齿条或齿轮凸轮等减速装置和变换机构，输出力与位移，进一步控制液压参数。R9009769194WRAE6W15-22/G24K31/F1VR9012061734WRA6WB07-22/G24N9K4/V-58R9789128324WRA6W03-22/G24K4/VR9789166394WRAE6E03-22/G24K31/A1VR9789166394WRAE6E03-22/G24K31/A1VR9002442384WRA6WA30-22/G24N9K4/VR9005559674WRAE10W1-30-22/G24N9K31/A1VR9005583554WRAE6E30-22/G24N9K31/A1VR9005583564WRAE10E60-22/G24N9K31/A1VR9005757654WRA10W1-60-22/G24N9K4/VR9005774244WRA10W30-22/G24K4/VR9007105304WRAE10W60-22/G24K31/F1VR9007368944WRAE6W03-22/G24N9K31/A1VR9007507184WRAE6EA15-22/G24N9K31/A1VR9007620724WRAE6W30-22/G24K31/F1VR9007840244WRA6W1-15-22/G24N9K4/V-589R9007873744WRA6WA07-22/G24N9K4/V-589R9009009874WRAE6W30-22/G24N9K31/A1VR9009009884WRAE10W60-22/G24N9K31/A1VR9009020954WRA6W30-22/G24N9K4/VR9009020974WRA10E60-22/G24N9K4/VR9009025374WRA6W1-30-22/G24N9K4/VR9009029404WRA6E30-22/G24N9K4/VR9009040104WRAE10E30-22/G24N9K31/F1VR9009041054WRA6E07-22/G24N9K4/V-589R9009044384WRA6E15-22/G24K4/VR9009044394WRA6E30-22/G24K4/V)
