一、进口德标波纹管截止阀概述

进口德标波纹管截止阀（威盾VTON），DIN standard bellows globe valve，也叫德标法兰波纹管截止阀，德标波纹管密封截止阀，德标铸钢波纹管截止阀，是指设计和制造采用德国DIN标准的波纹管密封截止阀，适用于公称压力PN1．6～16MPa，工作温度-29～350℃的易燃、易爆、剧毒、毒性流体、高温导热油、液氨等介质。

美国威盾德标波纹管截止阀广泛应用于：石油化工、化纤纺织、塑料造纸、电力钢铁、印染橡胶、天然气等其它气体系统中，乙二醇等工业流体。

The German standard bellows globe valve (VTON), also known as the German standard flange bellows globe valve, German standard bellows sealed globe valve, and German standard cast steel bellows globe valve, refers to a bellows sealed globe valve designed and manufactured using the German DIN standard, suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature heat transfer oil, liquid ammonia, and other media with a nominal pressure of PN1.6-16MPa and a working temperature of -29-350 ℃.

The American Weidun German standard corrugated pipe globe valve is widely used in other gas systems such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, natural gas, and industrial fluids such as ethylene glycol.

二、进口德标波纹管截止阀结构特点

1、产品结构合理、密封可靠，双重坚固耐用的波纹管密封设计（波纹管+填料），保证阀杆的零泄漏。没有流体损失，提高工厂设备安全。并符合国际密封标准。
2、密封面堆焊Co基硬质合金、耐磨、耐腐、抗摩擦性能好、使用寿命长
3、阀杆调质及表面氮化处理，有良好的抗腐和抗摩擦性能；阀杆升降位置指示，更直观

1. The product structure is reasonable, the sealing is reliable, and the double sturdy and durable corrugated pipe sealing design (corrugated pipe+packing) ensures zero leakage of the valve stem. No fluid loss, improving the safety of factory equipment. And comply with international sealing standards.

2. Sealing surface welding with Co based hard alloy, wear-resistant, corrosion-resistant, good friction resistance, and long service life

3. Valve stem quenching and surface nitriding treatment, with good corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive
