KITZ SCT’s Manufacturing

Development and production system

KITZ SCT’s concept of research and development

We are committed to carrying out new technology research surveys throughout our development departments, sales departments and production departments in order to continue to provide highly reliable products that satisfy all of our customers.

Manufacturing meeting customer demands for not only general-products but also special and high value added systems

KITZ SCT is creating fluid control devices that offer the highest level of safety, durability and reliability. A unique development and testing system to continue to create high-value added products has been constructed. KITZ SCT promises to continue to provide our customers with products that meet customer demands based on the spirit of challenge as a development-oriented company.

Unique technology responding to our global customers’ trust

Based on market-oriented ideas and direction, the KITZ Group continues to improve our technological capabilities in various fields, while fostering higher-functionality and higher-precision products and developing production technology in order to deliver high-quality and creative products to our customers.


Temperature distribution analysis

Realization of excellent thermal uniformity

We have developed optimum heating technology to stably supply vaporized/sublimed compound materials to points of use. As well, we have developed the heating technology to secure excellent thermal uniformity for reducing the accumulation of by-products in valves.


Japan’s first 70MPa class ball valve for hydrogen stations

high pressure valve series for hydrogen station

We are committed to developing products requiring high pressure technology for the semiconductor industry and for hydrogen filling facilities for fuel cell vehicles (FCV) according to laws and regulations as a high pressure gas accredited factory.


Pressure can be controlled from high vacuum to the vicinity of atmospheric pressure.

Realization of wide-ranging pressure control

In order to realize wide-ranging vacuum pressure controls from high vacuum to low vacuum areas, we are creating optimum pressure control technology by fusing our control technology and original mechanical technology.

Product development evolving with the world’s leading technological capabilities

  • APC butterfly valve

    Due to our original structure of continuous operation of the seat ring and flapper, the 3 functions of valve opening/closing, slow vacuum, and pressure control are realized by one valve. Our unique design improves the durability of the O-ring at the flapper.

  • Heated Isolation Valve

    With original heating structure, by heaters attached outside the valve body and inside the bellows, cold spots are eliminated and the accumulation of by-products are reduced.
    Our internal and external heating will reduce the frequency of valve maintenance extending MTTF of the valve improving productivity.

  • Heated gate valve

    By securing excellent thermal uniformity through individual temperature control of heaters outside the body and inside the valve gate, the accumulation of by-products is reduced and the maintenance cycle is extended. Also, through the adoption of a low friction, non-sliding structure, particle generation is reduced during valve opening and closing.

  • Integrated gas system

    Through the adoption of KITZ SCT’s unique IGS B-seal (center-lock) method, this gas system is space-saving and excellent in maintainability. The B-seal (center-lock) allows quick replacement of valves and other devices by a single nut, like changing racing car tires.

KITZ SCT’s development system

KITZ SCT develops new products with its development & design, quality assurance, production management, manufacturing, and sales departments all in a cooperative effort. By developing new products from various perspectives, we quickly provide products that meet customer needs. We are also committed to developing new products on a day-to-day basis through the adoption of new technologies.
