不銹鋼蝶閥的型號通常由以下幾部分組成：

　　The model of stainless steel butterfly valve usually consists of the following parts:

　　D ：代表閥門類型，即蝶閥。

　　D ： Representing valve type, namely butterfly valve.

　　驅動裝置 ：如手柄操作、蝸輪驅動、氣動、電動等。

　　Drive devices: such as handle operation, worm gear drive, pneumatic, electric, etc.

　　連接方式 ：如法蘭連接。

　　Connection method: such as flange connection.

　　結構形式 ：如中心密封、單偏心、雙偏心、三偏心等。

　　Structural forms: such as center seal, single eccentricity, double eccentricity, triple eccentricity, etc.

　　閥座堆焊 ：如不銹鋼。

　　Valve seat welding: such as stainless steel.

　　公稱壓力 ：如1.6MPa。

　　Nominal pressure: such as 1.6MPa.

　　閥體材料 ：如不銹鋼CF8。

　　Valve body material: such as stainless steel CF8.

　　以下是一些常用的不銹鋼蝶閥型號示例：

　　Here are some common examples of stainless steel butterfly valve models:

　　軟密封不銹鋼法蘭蝶閥：

　　Soft sealed stainless steel flange butterfly valve:

　　D41X-16P（手柄操作）

　　D41X-16P (handle operated)

　　D341X-16P（蝸輪驅動）

　　D341X-16P (worm gear drive)

　　D641X-16P（氣動）

　　D641X-16P (Pneumatic)

　　D941X-16P（電動）

　　D941X-16P (electric)

　　硬密封不銹鋼法蘭蝶閥：

　　Hard sealed stainless steel flange butterfly valve:

　　D343W-16P（蝸輪）

　　D343W-16P (worm gear)

　　D643W-16P（氣動）

　　D643W-16P (Pneumatic)

　　D943W-16P（電動）

　　D943W-16P (electric)

　　這些型號中的字母和數字分別代表不同的參數和特性，如D代表蝶閥類型，3代表蝸輪驅動，4代表法蘭連接，W代表閥座堆焊不銹鋼，-16P代表公稱壓力為1.6MPa，P代表閥體材料為不銹鋼CF8。

　　The letters and numbers in these models represent different parameters and characteristics, such as D for butterfly valve type, 3 for worm gear drive, 4 for flange connection, W for seat overlay stainless steel- 16P represents a nominal pressure of 1.6MPa, and P represents a valve body material of stainless steel CF8.
