品牌：RETZ瑞茨/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……

(二片式,三片式)進口電動螺紋球閥依靠旋轉(zhuǎn)閥芯來使閥門暢通或閉塞。閥座采用彈性密封結(jié)構(gòu)，閥桿采用有倒密封的下裝式結(jié)構(gòu)，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(shè)計特色 Design features 

開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)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(zhì)隔離，介質(zhì)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(zhuǎn)刻度盤頂部旋鈕即可輕松完成電動執(zhí)行機構(gòu)與閥門連接后的電氣、機械位置校準調(diào)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(shè)計、無阻隔 Full bore design, no barrier

防火型式密封結(jié)構(gòu) Fireproof type seal structure

防噴出閥桿結(jié)構(gòu) Anti-spray valve stem structure

防低泄漏設(shè)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(guān)和調(diào)節(jié)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(chǎn)品結(jié)構(gòu)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
