RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……(二片式,三片式)进口电动螺纹球阀依靠旋转阀芯来使阀门畅通或闭塞。阀座采用弹性密封结构，阀杆采用有倒密封的下装式结构，阀腔异常升压时，阀杆不会被冲击。retz The imported electric threaded ball valve (two piece, three piece) relies on a rotating valve to make the valve smooth or blocked. The valve seat adopts an elastic sealing structure, and the valve stem adopts a bottom mounted structure with an inverted seal. When the valve chamber is abnormally pressurized, the valve stem will not be impacted
进口电动焊接球阀设计特色 Design features
开闭迅速，从全开到全关只要旋转90°，便于远距离的控制Quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control
在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface
旋转刻度盘顶部旋钮即可轻松完成电动执行机构与阀门连接后的电气、机械位置校准调试 Rotate the top knob of the dial to easily complete the electrical and mechanical position calibration and debugging of the electric actuator connected to the valve
全通径式设计、无阻隔 Full bore design, no barrier
防火型式密封结构 Fireproof type seal structure
防喷出阀杆结构 Anti-spray valve stem structure
防低泄漏设计填料及填料函 Low leakage prevention design packing and stuffing box
ISO 5211连接平台 ISO 5211 connection platform
适用于开关和调节动作等多种控制方式，广泛替代各种电磁阀 Suitable for various control methods such as switching and regulating actions, widely replacing various solenoid valves
具有自洁功能，有效*证管路的畅通。流道简单，相对于电磁阀产品结构的S型流道，具有流通阻力小，无卡阻 Equipped with self-cleaning function, effectively ensuring the smoothness of pipelines. The flow channel is simple, and compared to the S-shaped flow channel of the solenoid valve product structure, it has low flow resistance and no jamming
具有自锁（自保持阀位）功能 Equipped with self-locking (self holding valve position) function
