一、进口铸钢法兰闸阀概述

进口铸钢法兰闸阀，Cast steel flanged gate valve，是指采用美国威盾优质上等的铸钢材质，采用法兰连接方式的闸阀。闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关，不适合作调节和节流。

美国威盾进口铸钢法兰闸阀主要产品有：进口铸钢闸阀，进口碳钢闸阀，进口美标闸阀，进口蒸汽闸阀，进口水用闸阀，进口气体闸阀，楔式闸阀、刀型闸阀、弹性座封闸阀、JIS日标、ANSI美标闸阀、夹套保温闸阀、浆液阀、锻钢闸阀、平板闸阀、暗杆闸阀、真空闸阀等系列产品。

Cast steel flange gate valve, Cast steel flanged gate valve， It refers to a gate valve made of high-quality cast steel material from the American shield and connected by flange. The opening and closing component of a gate valve is the gate, and the direction of the gate's movement is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and is not suitable for adjustment and throttling.

The main products of cast steel flange gate valves include: imported cast steel gate valves, imported carbon steel gate valves, imported American standard gate valves, imported steam gate valves, imported water gate valves, imported gas gate valves, wedge gate valves, knife gate valves, elastic seat seal gate valves JIS Japanese standard ANSI American standard gate valves, jacketed insulation gate valves, slurry valves, forged steel gate valves, flat gate valves, non rising stem gate valves, vacuum gate valves and other series of products.

三、进口铸钢法兰闸阀优点

1．铸钢法兰闸阀流体阻力小，密封面受介质的冲刷和侵蚀小。

2．铸钢法兰闸阀开闭较省力。

3．铸钢法兰闸阀介质流向不受限制，不扰流、不降低压力。

4．铸钢法兰闸阀形体简单，结构长度短，制造工艺性好，适用范围广。

1. Cast steel flange gate valves have low fluid resistance, and the sealing surface is less susceptible to erosion and erosion by the medium.

2. The opening and closing of cast steel flange gate valves is more labor-saving.

3. The medium flow direction of the cast steel flange gate valve is not restricted, does not disturb flow, and does not reduce pressure.

4. The cast steel flange gate valve has a simple shape, short structural length, good manufacturing process, and a wide range of applications.
