SBP Pressure Balanced Cage and Port Guiding Parabolic Plug Type
SBP series has both optional structures of metal and soft sealing. Combined with
complex piston rings, SBP presents excellent seal performance. The series with
balanced trims requires much lower control forces than valves without balancing for
very high pressure drops. Parabolic column plug ensure large rangebility, precise
flow characteristics and not being locked.
SBP series is best suitable to large pressure drop ratio, wide temperature change
and particle conditions, etc.
