品牌：RETZ/我們一直致力于流體控制和測控領域的持續(xù)創(chuàng)新，始于2005……
(法蘭，內(nèi)螺紋)氣動高壓球閥主要用于截斷或接通管路中的介質(zhì)，亦可用于流體的調(diào)節(jié)與控制，結(jié)構緊湊，密封可靠，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，易于操作和維修，適用于水、溶劑、酸和天然氣等一般工作介質(zhì)The imported pneumatic high-pressure ball valve (flange, internal thread) is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It has a compact structure, reliable sealing, and the sealing surface and spherical surface are often in a closed state, not easily eroded by the medium, easy to operate and maintain, suitable for general working media such as water, solvent, acid, and natural gas

進口氣動高壓球閥特點Characteristic
全流量流通，啟閉迅速,從全開到全關只要旋轉(zhuǎn)90° Full flow circulation, quick opening and closing, and 90 ° rotation from full opening to full closing
流體阻力小，全通徑的球閥基本沒有流阻 The fluid resistance is small, and the full bore ball valve basically has no flow resistance
耐高壓，啟閉迅速,扭矩低，無泄漏，不需要手工重調(diào)密封件 High pressure resistance, quick opening and closing, low
緊密可靠,密封面材料為PTFE，密封性好，能實現(xiàn)完全密封。在真空系統(tǒng)中也已廣泛使用 Tight atorque, no leakage, no need to manually readjust the sealsnd reliable, the sealing surface material is PTFE, with good sealing performance, and can achieve complete sealing. It has also been widely used in vacuum systems
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 the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface
