Product Category详细介绍
SN5系列软密封球阀是一种全通径直通球阀,于2017年获得API 6D认证, 2019年获得API 607、TÜV ISO15848、BV SIL3认证。该类球阀分浮动式和固定式 两种,其球体只需旋转 90°就能实现阀的全开或全关。该球阀切断性能优异,流体 压降损失最小,同时具有阀杆防飞出,以及防火、防静电等功能,适合于液体、气 体等各种流体的切断控制。
SN5 series soft-seal O-type ball control valves are offered in two basic structures, floating ball (below DN200) and trunnion mounted ba 11 (above DN250). Special elastic lip seal structure not only ensure sealing is reliable, but also has good self-cleaning effect for viscosity medium when it coordinates with cylindrical flow path, especially has shearing and block-risistant functions to the fluids with fiber. Full-port design , small fluid pressure loss and different metal and nonmetal combinations can guarantee reliably conveying and cutting . SN5 series are characterized by compact structure, effective handle, smooth operation and long lifetime.
