SN5系列軟密封球閥是一種全通徑直通球閥,于2017年獲得API 6D認證, 2019年獲得API 607、TÜV ISO15848、BV SIL3認證。該類球閥分浮動式和固定式 兩種,其球體只需旋轉 90°就能實現(xiàn)閥的全開或全關。該球閥切斷性能優(yōu)異,流體 壓降損失最小,同時具有閥桿防飛出,以及防火、防靜電等功能,適合于液體、氣 體等各種流體的切斷控制。
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.
