Yuken Kogyo, Co. Ltd.


High efficiency piston pumps.

 Yuken offers low noise/high efficiency, swash plate type variable displacement piston pumps. These pumps have been developed by Yuken’s leading hydraulic engineers and provide a diverse lineup to meet a wide range of application requirements. 

Directional Valves

Solenoid operated directional valves


These valve are used for shifting oil flow direction of hydraulic circuit and for actuator starting/stopping as well as the operating direction shifting of actuator.

Electric Motors

Hollow shaft, close coupled electric motors

 High Speed Linear Servo Valves - with Onboard Electronics. Achieve up to 450 Hz performance, less than 0.1% hysterisis, and superior contamination resistance. 

High Speed Proportional Directional & Flow Control with On Board Electronics

High speed linear servo valves

 Closed loop, high response type proportional electro-hydraulic directional and flow control valves with on board electronics. Two direct type models with a maximum rated flow rate up to 80 l/min (@.ΔP=1MPa) are available. Two different available models of two stage OBE valves have a maximum rated flow rate up to 500 L/min (ΔP=0.5MPa (72 psi) at each port). 

Modular Stack Valves

Modular Stack Valves

 YUKEN’s Modular Valves are stack type valves, and require no piping. They not only rationalize system build, but they also meet the technical requirements for a variety of hydraulic systems. Stacking systems is a new era in hydraulics. 


Hydraulic actuators and cylinders

 YUKEN’s “CJT” Series Hydraulic Cylinders are provided with many mounting types so that they can be used for wide use of general purpose industrial machines such as machine tools. Moreover, Switch-Set “CJT” Series Hydraulic Cylinders with a proximity switch which facilitates detecting a position with a slide proximity switch on the cylinder body is also available. 

About Yuken


YUKEN had its beginning in 1929 as an auto repair facility, started by Mr. Uichi Yuki. It grew into a machine tool builder in 1931. Hydraulic honing machines followed in 1940. The manufacturing of this equipment brought about the development of hydraulic vane pumps and control valves, which established a base for the manufacturing of hydraulic equipment.A Company by the name of Yuatsukiki Kenkyujo was formed in 1952, with $12,000.00 capitalization. In 1956 this company was reorganized as YUKEN KOGYO Co. Ltd. with $60,000.00 capitalization. A sales office was established in Osaka, Japan in 1959 followed by a factory in Fujisawa in 1960. In 1961 YUKEN Machinery Co. Ltd. was formed.

1962 saw the company listed on the Tokyo Stock Exchange with $2,000,000.00 capitalization. In 1964 the main office was moved to its present location in Fujisawa. A sales office was established in Tokyo in 1967. A manufacturing joint-venture commenced operations in 1969 under the name Taiwan Hydraulics Mfg. Co., Ltd.The stock of YUKEN was added to the Osaka Stock Exchange in 1969 with $9,100,000.00 capitalization. In forty (40) years YUKEN went from an auto repair shop to a publicly traded company.Since then YUKEN has continued to expand its line of hydraulic products as well as certain types of machinery dependent on hydraulic power. Currently, YUKEN has offices throughout Japan, and has expanded considerably with offices, plants and affiliated business relationships in the United Kingdom, Hong Kong, China, Taiwan, India and now the United States and Canada.YUKEN Kogyo Co. Ltd. is publicly traded on two (2) stock exchanges. They employ eight hundred (800) people and have sales exceeding ¥20,000,000,000.YUKEN has enjoyed a very successful and innovative past. Its future is directed toward significant growth and achievements in the Fluid Power Industry.
