阀门电机转矩符合阀门的启闭转矩特性。一般阀门开启和关闭-短时间内所需的转矩值高1/ 3 , 故阀门-电机的特点是启动力矩高3 倍3 倍。

阀门-电机设计时转子形状细长。因而高速转动的电机在阀门关闭时给阀门密封附加的惯性载荷小, 又不会使阀门密封面损坏。

由于阀门的操作是断续性的短时工作制10min , 有的国外产品时间为 , 无接线盒, 自冷却式ip5 , 5ip68 为潜水型电机。ydf2阀门电动装置-电机主要型号有：ydf2-111-4 ydf2-112-4 ydf2-121-4 ydf2-211-4 ydf2-212-4 ydf2-221-4 ydf2-222-4 ydf2-231-4 ydf2-311-4 ydf2-312-4 ydf2-321-4 ydf2-322-4 ydf2-411-4 ydf2-421-4 ydf2-422-4 ydf2-431-4
