進口電動焊接球閥 對焊 承插焊電動球閥

品牌：retz瑞茨/我們一直致力于流體控制和測控領域的持續創新，始于2005……
(二片式,三片式)進口電動螺紋球閥依靠旋轉閥芯來使閥門暢通或閉塞。閥座采用彈性密封結構，閥桿采用有倒密封的下裝式結構，閥腔異常升壓時，閥桿不會被沖擊。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
進口電動焊接球閥設計特色 design features
開閉迅速，從全開到全關只要旋轉90°，便于遠距離的控制quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control
在全開或全閉時，球體和閥座的密封面與介質隔離，介質通過時，不會引起閥門密封面的侵蝕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
旋轉刻度盤頂部旋鈕即可輕松完成電動執行機構與閥門連接后的電氣、機械位置校準調試 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
全通徑式設計、無阻隔 full bore design, no barrier
防火型式密封結構 fireproof type seal structure
防噴出閥桿結構 anti-spray valve stem structure
防低泄漏設計填料及填料函 low leakage prevention design packing and stuffing box
iso 5211連接平臺 iso 5211 connection platform
適用于開關和調節動作等多種控制方式，廣泛替代各種電磁閥 suitable for various control methods such as switching and regulating actions, widely replacing various solenoid valves
具有自潔功能，有效保證管路的暢通。流道簡單，相對于電磁閥產品結構的s型流道，具有流通阻力小，無卡阻 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
具有自鎖（自保持閥位）功能 equipped with self-locking (self holding valve position) function
