Control Valve Assy

Develop and Product in Integrated System

For years, TOSOK has been developing precision technologies for the production of gauges and the technologies supporting the systemization of the mechatronics parts, and we have a wealth of experience in jointly developing products with automobile manufactures and unit manufactures.
Based on these experiences (know-how), we are developing and manufacturing control valve assy that are equivalent to the heart of Automatic Transmission(AT) and Continuously Variable Transmission (CVT) .
Possible to provide control valve assy with high quality at competitive price by integrated system of production of solenoid valves and spool valves as a component of control valve.
TOSOK can satisfy sophisticated and various needs in the market.

Solenoid Valves

High reliability based on the performance over the years

TOSOK has a wealth of experience in jointly developing products with automobile manufactures and unit manufactures.
Based on these experiences, we are developing and manufacturing “Solenoid Valve” with high quality and reliability.
Our products can manage pilot control and direct control and it contributes to compactness as well as light weight of products.
Our engineering know-how which we gain in automotive industries can apply to the various scene and usage where flow control of oil, water and air are required.

Electric Oil Pump

Promote electric products for end dependence on fossil fuels

The Electric Oil Pump (EOP) of high efficiency, high accuracy and high reliability is provided by the collaboration of motor technology of NIDEC Co., Ltd and our in-vehicle technology.
Miniaturization is realized by adoption of integrated structure.
The durability is improved by adoption of the brushless motor. EOP can apply to transmission control pressure securing when engine shutdown on idol stop vehicles and hybrid electric vehicles and it also can use for cooling the driving motor on electric vehicles.
