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Theimported pneumatic high-pressure ball valve (flange, internal thread) is mainled to cut off or connect the medium in the pipeline, and can also beed forfluid regulation and control. It has apact structure, reliable sealing, andthe sealing surface and spherical surface are often in a closed state, noteasily eroded by the medium, easy to operate and maintain, suitable for generalworking media such as water, solvent, acid, and natural gas

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 flowcirculation, quick opening and closing, and 90 ° rotation from full opening tofull 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 fullbore 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 Highpressure 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 Tightatorque, no leakage, no need to manually readt the sealsnd reliable, thesealing surface material is PTFE, with good sealing performance, and canachieveplete sealing. It has also been widelyed 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, thesealing surfaces of the ball and valve seat are isolated from the medium. Whenthe medium passes through, it will not ce erosion of the valve sealingsurface
