一、KQ41F法兰抗硫球阀概述：
KQ41F法兰抗硫球阀是根据用户的需求，为满足在硫化环境下的抗硫化就力裂化的要求，我们从设计，选材、制造、试验、表面处理及涂漆都严格按美国腐蚀化工程师协会NACE的有关标准要求进行。
KQ41F法兰抗硫球阀不仅选材广泛且内件材料均采用表面镀镍或316材质、密封圈采用特制的聚合物材料。使阀门不仅防腐蚀，抗硫化能力强，防火、防静电、密封性能好，适用压力与温度范围广，全通径与缩经齐备，并可配多种驱动装置，是化工、石油炼制、油气开采与输送系统理想的用阀选择。
公称通径：DN50-400mm 2"-16"
缩径：DN50-450mm 2"-18"
公称压力：PN2.5-10.0MPa
CLASS：150-900Lb
适用温度：－196℃-300℃
