美标法兰球阀

Q41F型PN16~PN64法兰球阀用于Class150~Class1500的各种管路上,用于截断或接通管路中的介质,选用不同的材质,可分别适用于水、蒸汽、油品、液化气、天然气、煤气、硝酸、醋酸、氧化性介质、尿素等多种介质。


【产品特点】
1、在各种阀门中,球阀的流动阻力小,全径球阀打开时,球体通道、阀体通道和连接管径相等并成一直径,介质几乎可以毫无损失的流过;
2、球阀旋转90°即可全关全开,启闭迅速。与相同规格的闸阀、截止阀比较、球阀体积小、重量轻,便于管道安装。

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
