一、进口蒸汽截止阀概述

进口蒸汽截止阀（威盾VTON），Steam globe valve，也叫蒸汽法兰截止阀，蒸汽铸钢截止阀，蒸汽高温截止阀，精铸蒸汽截止阀，是指安装在蒸汽管道上，用于控制蒸汽的开启和关闭的截止阀。

美国威盾蒸汽截止阀采用不锈钢或者钛合金波纹管作为阀杆密封元件，可使阀杆部位无泄漏，以防止蒸汽外漏的截止阀。广泛适用于食品、医药、石油、化工、天然气、钢铁、环保、造纸等输送管路中做蒸汽介质切断或流通。

Steam globe valve (VTON), also known as steam flange globe valve, steam cast steel globe valve, steam high-temperature globe valve, precision cast steam globe valve, refers to a globe valve installed on steam pipelines to control the opening and closing of steam.

The American Shield steam globe valve uses stainless steel or titanium alloy bellows as the valve stem sealing element, which can prevent steam leakage from the valve stem and prevent steam leakage. Widely applicable for cutting off or circulating steam media in transportation pipelines such as food, medicine, petroleum, chemical, natural gas, steel, environmental protection, and papermaking.

三、进口蒸汽截止阀产品特点

1、进口蒸汽截止阀结构简单，制造和维修比较方便

2、进口蒸汽截止阀工作行程小，启闭时间短

3、进口蒸汽截止阀密封性好，密封面间磨擦力小，寿命较长

4、在高温情况下，阀杆不与介质接触，确保阀杆零泄漏。

5、保证足够的强度和韧性，可以开关上万次。

6、手轮采用人体工程学设计，使用寿命更长，操作轻松便捷。

1. The steam shut-off valve has a simple structure and is easy to manufacture and maintain

2. The working stroke of the steam shut-off valve is small, and the opening and closing time is short

3. The steam shut-off valve has good sealing performance, low friction between sealing surfaces, and a long service life

4. Under high temperature conditions, the valve stem does not come into contact with the medium, ensuring zero leakage of the valve stem.

5. Ensuring sufficient strength and toughness, it can be switched on and off tens of thousands of times.

6. The handwheel adopts ergonomic design, with a longer service life and easy and convenient operation.
