京蝶阀门从事阀门行业已有20年的历史，一直以创新技术为宗旨，公司主打产品有蝶阀、闸阀、止回阀、过滤器等
该阀是通过电磁阀的导控实现准确的开启或关闭，用于泵的出口处，防止介质倒流的逆止控制阀，当泵即将停止供水前，阀门先行缓闭 90％ 左右，防止突然停泵而产生的水锤和水击声，当泵*停止后，阀门再*关闭，防止泵出现水的回流，有效地保护水泵，免受回流的冲击而产生反转，该阀有效防止水锤和水击声，密封可靠、动作平稳、使用寿命长。电磁阀可采用交流电220V或直流电24V。 Used at the pump outlet to carry out an accurate open or close via the pilot control of the solenoid valve and。as a check control valve，to prevent the medium from back-flow．When the pump is about to stop water supply，it is slowly closed by about 90％ first to prevent both water hammer and water shock noise from being produced due to sudden stop of the pump and．when the pump stops compley．it is fully closed t0 prevent the water from back flow with the pump so as to effectively protect it from counter movement due to the shock of the back-flow This valve can effectively prevent water hammer and wa-ter shock noise．be reliably sealed and long time used and stably move The solenoid valve can use either AC220V or DC24V power.
