Valqua Group

- Since our founding in 1927, we at the VALQUA Group have worked tirelessly to offer our customers both the “value” and “quality” that forms our name, and have supported and contributed to the development of the Japanese economy as a pioneer of industrial seal products and processed fluororesin products.

- At present, the VALQUA Group is expanding its business in 3 major product areas: the “Seal Products Business”, which involves the development of seal materials for piping and equipment used in various industries, such as petroleum refining, petrochemistry, ironmaking, energy plants, automobiles, hydraulic-pneumatic equipment, construction equipment,and semiconductor manufacturing equipment; the “High-performance Plastics Products Business”, which involves products predominantly utilizing fluorocarbon resin with a variety of different functions; and “Silicon Wafer Reclaim and Other Businesses” that have a lot of growth potential and will help decrease our impact on the environment.

- As business models have changed significantly across the world over the past few years as a result of evolutions in Al and loT, we at the VALQUA Group have been developing products using our advanced proprietary technologies, and working toward reforms that will allow us to fully leverage our Group's strengths through collaborations with businesses that have revolutionary technologies, service development, and know-how, thereby contributing to the resolution of social issues in various fields, and the creation of a sustainable society.

- As the VALQUA Group heads toward its 100th anniversary in 2027, and looks further beyond that milestone , we are striving to become a "challenging company that challenges the future and the unknown," will create new forms of added value, realize sound and sustainable growth, and meet the expectations of our customers.
