Koso 6300LA/501G Koso 5200LA/550G Koso Vietnam, Nihon Koso Vietnam
501G series is our latest cage guide control valve of large Cv value, and of dynamic stability. It is suitable to a variety of heavy duty services. This series is characterized by pressure balanced type trim for high pressure drops.
550G Series provides control valves that meet low noise and anti-cavitation requirements by incorporating a multi-hole type cages, instead of the standard cages, in the 501G Series cage guided control valves.
All the parts except the multi-hole cage are interchangeable with the parts of the 501G Series accordingly.
For those severe fluid conditions that cannot be covered by this Series, please select KOSO velocity control trim type.
