品牌：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……
(法兰，内螺纹)气动高压球阀主要用于截断或接通管路中的介质，亦可用于流体的调节与控制，结构紧凑，密封可靠，密封面与球面常在闭合状态，不易被介质冲蚀，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质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
进口气动高压球阀产品详情 Product details
(法兰，内螺纹)气动高压球阀旋转控制芯轴使球体从开启位置切换到关闭位置，系统压力将球体推向密封碗的无压制侧并无泄漏地切断液流 RETZ (Flange, internal thread) The inlet pneumatic high-pressure ball valve rotates the control spindle to switch the ball from the open position to the closed position, and the system pressure pushes the ball to the non pressing side of the sealing bowl to cut off the liquid flow without leakage

进口气动高压球阀特点Characteristic
全流量流通，启闭迅速,从全开到全关只要旋转90° Full flow circulation, quick opening and closing, and 90 ° rotation from full opening to full closing
流体阻力小，全通径的球阀基本没有流阻 The fluid resistance is small, and the full bore ball valve basically has no flow resistance
耐高压，启闭迅速,扭矩低，无泄漏，不需要手工重调密封件 High pressure resistance, quick opening and closing, low
紧密可靠,密封面材料为PTFE，密封性好，能实现完全密封。在真空系统中也已广泛使用 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 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
