Product Category详细介绍
LN8系列顶导向单座控制阀是一种顶部导向、柱塞型单座控制阀。于2019年获 得TÜV ISO15848 认证。具有控制精度高,密封性能好,结构简单,通用性强等特 点。适宜于要求控制精度较高的工况流体控制。可采用波纹管密封型。已在精细化 工、石化、医药等行业有数千次应用业绩。 产品性能: -采用模块化设计理念,将美日流派高精度控制和德国流派模块化理念相结合; -阀体内腔呈S型分布,光滑无死角;阀体内部有导流翼,能减少阀体内部介质 的互相作用力,减少气蚀的发生;
LN81/82 series are characterized by insensitive to impurities and excellent sealing performance. Seat retaining cage is available for all trim designs to optimize flow conditions and resist erosion by cavitation. Fast and easy to maintenance due to its quick-changeable trim combination. LN81 series can be used in a wide range of applications, especially suitable for the fluid with entrained particle and larger temperature variety.LN82 series, with perforated cylinder Plug, can effectively protect sealing surface of seat to be damaged by high speed flow scoured.
