一、进口铸钢/碳钢闸阀概述

进口铸钢/碳钢闸阀，Cast steel gate valve，是指采用美国威盾优质上等的铸钢/碳钢/WCB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。是最常用的截断阀之一，主要用来接通或截断管路中的介质，不适用于调节介质流量。铸钢闸阀适用的压力、温度及口径范围很大，尤其适用于中、大口径的管道。

美国威盾进口铸钢/碳钢闸阀主要产品有：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/carbon steel gate valves, Cast steel gate valve， It refers to a gate valve made of high-quality cast steel/carbon steel/WCB 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. It is one of the most commonly used shut-off valves, mainly used to connect or cut off the medium in the pipeline, and is not suitable for regulating the medium flow rate. Cast steel gate valves are suitable for a wide range of pressure, temperature, and diameter, especially for medium and large diameter pipelines.

The main products of American Weidun imported cast steel/carbon steel gate valves include: cast steel gate valves, carbon steel gate valves, American standard gate valves, steam gate valves, water gate valves, 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.
