The KOSO series 501T (globe) and 511T (angle) are top guided single seated control valves with unbalanced and balanced plug designs. Compact and simple, they cover small to large flow capacities for cavitation-free liquid service as well as steam and gas service within noise limits. For severe duty, the multi-hole cage guided 550G/560G and KOSO VECTOR series are available.
Designed by Nihon KOSO (Japan) and manufactured by KOSO India in Nashik to ASME B16.34, with quality systems to ISO 9001 and API Spec Q1.
Key features
- High trim capacity: wide range of trim Cv per valve size, giving high flow capacity per size
- Suitable for services with solid particles
- Tight shut-off easily achieved, up to ANSI/FCI 70-2 Class VI
- Fine flow control and wide rangeability with contoured plug design
- Easy maintenance: all internal components removable from the top
- Pneumatic diaphragm, pneumatic cylinder, electric or hydraulic actuation
