Smart Valve Positioner
KGP5000 series smart valve positioner is a control device mounted on the pneumatic actuator for control valve
KGP5000 series smart valve positioner is a control device mounted on the pneumatic actuator for control valve, which positions a control valve according to a 4 to 20mA electric input signal from a higher-level control system or a control device.
Position feedback control system which receives feedback signal mapped to the desired valve travel and compares both input signal and feedback signal enables accurate positioning of a control valve.
In addition, it is possible to use this positioner in order to operate various types of pneumatic actuator such as single and double acting, linear and rotary motion actuators.
Furthermore, the positioner utilizing digital techniques performs the functions of advanced PID controller, local user interface using LCD, diagnostics utilizing sensing techniques with potentiometers and internal pressure sensors.
Such features enable an easy installation and calibration, an effective monitoring and an efficient process management relevant to operations and maintenance.
Electro-Pneumatic Positioner
This series is for positioning of pneumatic actuator operated control valves
This series is for positioning of pneumatic actuator oper-ated cotrol valves. Input signal 4 to 20mA DC is changed to air pressure. Accurate positioning is achieved by having valve position feedback from valve stem.
Pneumatic Positioner
Same series as EP800 but this works having pneumatic signal (20 to 100Kpa
Same series as EP800 but this works having pneumatic signal (20 to 100Kpa). Also double acting and single acting types are available.

3-Way Diverting Globe Valves
Diverting type that divides the flow into two directions and mixing type that converges two flows into one are available.
Diverting type that divides the flow into two directions and mixing type that converges two flows into one are available. For valve size 2.5 in.(65A) or under, 531F(mixing type) is also used as diverting type with no functional problem.
Cage Guided
501G series is our latest cage guide control valve of large Cv value, and of dynamic stability.
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.
Top Guided Single Seat Globe Valves
KOSO top-guided control valves are compact and simple structured
KOSO top-guided control valves are compact and simple structured. They are usable in a broad scope of applications, including all cavitation-free liquid services as well as steam and gas services that meet noise regulations.
Aiming at quick delivery and low prices, 551T is limited to JIS 10K, ANSI(JPI)150 lbs. with no optional features. 520T covers minimum flow applications, with its small plug specially designed not to break off.
Electro-Hydraulic Actuators
The M-MAC series is the electro-hydraulic actuator which combines the power of hydraulics
The M-MAC series is the electro-hydraulic actuator which combines the power of hydraulics, the reliability of solid state electronics 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 allows 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.
Microprocessor Controlled Actuators
This Series represents intelligent digital actuators targeting the control method of the next generation.
They are process control devices of multi-function hybrid structure incorporationg computer functions to fully utilize advan-tages of both electric and hydraulic types, ie., high speed and large output. Major components are digital motor, gear pump and electronic circuit. Unique hydraulic Flow Match System (pat-ented) controlled by direct digital signals secures stabilized high speed response and high accurancy action. Fail safe upon power loss. Furthermore, with three kinds of power modules that have redundancy and high power, electric safety is enhanced. With this Series, we have come closest ever to the concept of “Maintenance free.
Solid State Electronic Actuators
Each product of this series drives and controls a control valve, with a motor driven by a full-electronic controller
Each product of this series drives and controls a control valve, with a motor driven by a full-electronic controller upon receipt of a signal (4 to 20 m ADC) from the controller. A product of 3500 series, which is of high-end type, executes critical control by means of a brushless DC servo, a product of 3600 series or 3620 series providing superior cost performance executes control by an AC reversible motor. Furthermore, a product of 3620 series, which is of motor built-in type, provides excellent heat radiation effect. In addition, explosion-proofing approved models are also replete. See here for models and details of specification.
