Guided by big area bushing and cage, working trims are of dynamic stability. The series is characterized by balanced trims and can endure very high pressure drops. It only needs small thrust force to reliably modulate. Perforated cylinder Plug can effectively protect the sealing surface of seat from being damaged by high speed flow scoured. Combined with complex piston rings, it also presents excellent seal performance.
SBC series suits normal and heavy duty applications.
