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℃
