Since its establishment, the KOSO group has
developed a diverse range of high-quality
control valves greatly contributing to the
implementation of process automation (PA) in
various industries.

In 1976, KOSO started to develop,

manufacture, and sell automation systems
utilizing the abundant experience and know-how
gained by that time. Today, even stronger from
strategic acquisitions, KOSO is able to offer a
complete line of automation systems, including
sensors, controllers, and computers.

KOSO stands ready to meet every customer

need with the best products available as they
strive to equip themselves with the total automa-
tion systems of the next century.

In severe services with high temperature and high differential pressure, KOSO’s multi-stage VECTORTM trim promises
accurate control and long life, free from cavitation erosion and noise problems, whether the fluid is compressive or
non-compressive. This Series is multi-advantageous in that its improved performance and durability allows mainte-
nance cost reduction and system simplification. Since such ancillaries as diffusers
and silencers are not necessary and equipment cost can
be reduced. With 500M, 500D and 500J VECTORTM trim
choices, depending on the fluid condition, the most suitable
model can be selected by comparing features.

550G: Multi-hole Cage Guided Control Valves

The 501G series is our latest cage guide control valve with large Cv value, and dynamic stability. It is suitable for a
variety of heavy duty services. This series is characterized by pressure balanced type trim for high pressure drops.

The 550G series provides control valves that meet low noise and anti-cavitation requirements by incorporating 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. For severe fluid conditions that cannot be
covered by this series, you can choose from KOSO’s VECTORTM velocity control trim options.

210C: Concentric segmental ball valves

This series is a concentric segmental ball valve for modulating applications. A V-notch cut at disc makes rangeability
larger and creates a shearing effect by disc and seal ring. Therefore, suitable to large rangeability service and/or con-
trol of fluids with entrained particles and/or slurry.

230C: Concentric segmental ball valves

This series is the same as the 210C series except that the stem penetrates the body and is supported by double gland
packing. The stem’s blow out force is set off in this construction making it suitable for heavier services such as high
pressure, high temperature service because of the heat expansion insulated stem design.

300W: Metal Seated Ball Valves

This ball valve series provides zero-leakage in several service applications with high temperature and/or high pres-
sure. The ball and seat are hard coated with chrome carbide or tungsten carbide using Koso’s HVOF coating system
to provide high erosion and abrasion resistance. They are mate-lapped based on our own technique to ensure 100%
sealing. Live loading also ensures zero emissions.

The ball never leaves the seat and wipes contaminants away. This self-cleaning action prevents interference and dam-
age from contaminants. Therefore, this valve is suitable for the slurry service the abrasive services.

This flexible valve design be easily adapted to the flow characteristics of the service condition by simply changing the
ball window shape.

610S: RING-SEAL type Butterfly Valves

This butterfly valve design features a metal seal ring with a cut-end which is set around the disc. This construction al-
lows for low seating force and better shut off performance. It also provides more resistance against very high operat-
ing temperatures. The seat ring’s thermal expansion with fluid temperature fluctuation makes the valve best suited to
high-temperature fluid applications.

Microprocessor Controlled Actuators

HIGH POWER·HIGH SPEED·HIGH PERFORMANCE ACTUATOR

This series of actuators represents the next generation of intelligent digital actuators. These are milti-function hybrid
process control devices incorporating computer functions to fully utilize the advantages of both electric and hydraulic
types, i.e., high speed and large output.

Major components are: digital motor, gear pump and electronic circuit. Unique hydraulic Flow Match System (patent-
ed) controlled by direct digital signals secures stabilized high speed response and high accuracy action. The actuators
feature a fail safe upon power loss. Furthermore, two kinds of power modules provide redundancy and high power to
enhance electric safety. With this series, we are closer than ever to the concept of “maintenance free.”

4800 SERIES ELECTRO-HYDRAULIC ACTUATORS

4800: Electro-Hydraulic Actuators The M-MAC series is the electro-hydraulic actuator which com-
bines the power of hydraulics, the reliability of solid state elec-
tronics and the flexibility of user-configured control. It features
a compact design, and all the major components of a hydraulic
system are packaged with a stand alone modular actuator,
which provides excellent value. Simply install, then hook up to
the appropriate electric power source. M-MAC series also al-
lows for precise positioning independent of load variation. The
motor only operates when motion is required and it achieves
the power consumption. The dedicated controller allows the
user to set the desired actuator operation parameters.

5200: Pneumatic Diaphragm Actuators

This series provides high performance, high power multi-spring diaphragm actuators that are compact and light-
weight. Receiving pneumatic or electric signals, the unit balances the force created when the diaphragm is air-pres-
sured through positioner and the force of compressed spring, so that the output shaft is controlled and placed at a set
position. Control of position by pneumatic signals (20~100Kpa) directly applied on the diaphragm is also possible. In
combination with KOSO’s positioner the 5200 pneumatic diaphragm actuators provide high accuracy position control.
