一、进口高温球阀概述

进口高温球阀（美国威盾VTON），High temperature ball valve，也叫高温法兰球阀，高温介质球阀，高温不锈钢球阀，高温流体球阀，是采用新型密封材料为阀座,经同类产品聚四氟乙烯做密封的球阀,使用寿命提高了3-5倍。具有性能稳定、密封可靠、磨擦力小、开关轻便、耐高温、耐磨、耐油、耐腐蚀、使用寿命长等优点，美国威盾VTON高温球阀与截止阀、柱塞阀、排污阀，结构长度相符，扩大了球阀使用范围，广泛用于石油、化工、橡胶、造纸、制药等行业，可替代截止阀、柱塞阀、快速排污阀。适用介质：水、蒸汽、导热油等酸类，使用温度：≤350℃。

High temperature ball valve (VTON), also known as high temperature flange ball valve, high temperature medium ball valve, high temperature stainless steel ball valve, and high temperature fluid ball valve, is a ball valve that uses a new sealing material as the valve seat and is sealed with similar products such as PTFE, which increases its service life by 3-5 times. With advantages such as stable performance, reliable sealing, low friction, lightweight switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life, the American Weidun VTON high-temperature ball valve is structurally consistent with globe valves, plunger valves, and drain valves, expanding the scope of ball valve use. It is widely used in industries such as petroleum, chemical, rubber, paper, and pharmaceuticals, and can replace globe valves, plunger valves, and fast drain valves. Applicable media: water, steam, heat transfer oil and other acids, operating temperature: ≤ 350 ℃.

二、进口高温球阀特点

进口高温球阀中的球体、密封圈采用了特殊的加工工艺和最新密封材料，使球体表面粗糙度和圆度达到标准要求，从而提高了密封性能和使用寿命、耐高温的能力。 顺时板动手柄带动阀杆驱动球体旋转，使介质顺利通过。

The ball and sealing ring in imported high-temperature ball valves adopt special processing technology and the latest sealing materials, which make the surface roughness and roundness of the ball meet the standard requirements, thereby improving sealing performance, service life, and high-temperature resistance. The timing plate moves the handle to drive the valve stem to rotate the ball, allowing the medium to pass smoothly.
