一、进口浮动软密封球阀概述

进口浮动软密封球阀（美国威盾VTON），Floating soft sealing ball valve，也叫浮动式软密封球阀，也叫浮动式球阀，软密封浮动球阀，是指采用铸钢或者不锈钢阀体，浮动球结构，四氟或者PPL软材料密封的球阀，用于 Class150~Class1500、PN16~PN63、JIS10K~JIS20K 的各种管路上，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、液化气、天然气、煤气、硝酸、醋酸、氧化性介质、尿素等多种介质。

Floating soft sealing ball valve (VTON), also known as floating soft sealing ball valve or floating ball valve, refers to a ball valve that uses cast steel or stainless steel valve body, floating ball structure, PTFE or PPL soft material sealing. It is used on various pipelines of Class150~Class1500, PN16~PN63, JIS10K~JIS20K, to cut off or connect the medium in the pipeline. Different materials are selected, and can be applied to various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc.

二、 进口浮动软密封球阀产品特点

1、在各种阀门中，球阀的流动阻力最小，全径球阀打开时，球体通道、阀体通道和连接管径相等并成一直径，介质几乎可以毫无损失的流过。

2、球阀旋转90°即可全关全开，启闭迅速。与相同规格的闸阀、截止阀比较、球阀体积小、重量轻，便于管道安装。

1. Among various valves, ball valves have the lowest flow resistance. When the full diameter ball valve is opened, the ball channel, valve body channel, and connecting pipe diameter are equal and form a diameter, and the medium can flow almost without any loss.

2. The ball valve can be fully closed and fully opened by rotating 90 °, with quick opening and closing. Compared with gate valves and globe valves of the same specifications, ball valves have a smaller volume and lighter weight, making them easier to install in pipelines.
