一、进口法兰式硬密封蝶阀产品概述

进口法兰式硬密封蝶阀（美国威盾VTON），Flange type hard seal butterfly valve，也叫法兰双偏心蝶阀，法兰三偏心蝶阀，法兰硬密封不锈钢蝶阀，是指采用法兰的连接方式，采用三偏心密封结构，阀座与蝶板几乎无磨损，具有越观越紧的密封功能密封圈选用不锈钢制作，具有金属硬密封和弹性密封的双重优点，无论在低温和高温的情况下，均具有优良的密封性能的蝶阀。

美国威盾VTON法兰式硬密封蝶阀主要产品有碳钢法兰硬密封蝶阀，不锈钢法兰硬密封蝶阀，电动法兰硬密封蝶阀，气动法兰硬密封蝶阀。

二、进口法兰式硬密封蝶阀产品特点

1、法兰式硬密封蝶阀具有耐腐蚀,使用寿命长等特点。
2、法兰式硬密封蝶阀蝶板密封面采用堆焊钴基硬质合金，密封面耐磨损，使用寿命长。
3、法兰式硬密封蝶阀大规格蝶板采用绗架结构，强度高，过流面积大，流阻小。
4、金属硬密封蝶阀具有双向密封功能，安装时不受介质流向的限制，也不受空间位置的影响，可在任何方向安装。
5、法兰式硬密封蝶阀驱动装置可以多工位（旋转90°或180°）安装，便于用户使用。

1. The flange type hard sealed butterfly valve has the characteristics of corrosion resistance and long service life.

2. The sealing surface of the flange type hard sealed butterfly valve butterfly plate is made of cobalt based hard alloy with overlay welding, which is wear-resistant and has a long service life.

3. The large size butterfly plate of the flange type hard sealed butterfly valve adopts a quilted frame structure, which has high strength, large flow area, and small flow resistance.

4. Metal hard sealed butterfly valves have a bi-directional sealing function, and are not limited by the flow direction of the medium or the influence of spatial position during installation. They can be installed in any direction.

5. The flange type hard sealed butterfly valve drive device can be installed at multiple workstations (rotating 90 ° or 180 °), making it convenient for users to use.
