KITZ Corporation

Established in 1951, KITZ is one of the world's leading manufacturers of valves, and Japan's largest. Major products include carbon steel valves, stainless steel valves, gray iron and ductile iron valves, bronze and brass valves, and valve actuators.

The Company aims to lead the general flow control industry by becoming the most versatile valve manufacturer. To fulfill this goal, KITZ has widened its product range and offered more convenient product sourcing to its customers. It has also employed the just-in-time production system to dramatically improve its production efficiency, particularly for smaller and more varied customer needs.

To maintain product quality and delivery, the Company continues to upgrade its production system, which includes in-house material foundries. And KITZ's quality assurance system ensures that, at all operating stages, the Company's materials, products, and services meet customer requirements.

KITZ Worldwide

KITZ extends support to customers in many ways. We offer quality products and reliably systemized distribution and maintenance networks. In addition, we cover markets worldwide by working closely with overseas sales agents, primarily through our overseas sales bases. The KITZ Group has established an overseas network which oversees branch offices and subsidiaries in the U.S., Germany, the U.K., Spain, the U.A.E., China, Thailand, India, and Singapore.

This network allows KITZ Corporation to cover all global markets as well as work with over 100 distributors to serve customers across the globe. To respond quickly to requests and problems concerning specific products, there is a network of KITZ Authorized Modification Shops that can modify and repair valves.

Product Technology

Originating as a producer of general purpose valves, KITZ has grown and evolved over the years to stay ahead of advancing customer needs. Today, we supply a broad line of fluid control devices extending from hand operated valves to automated models, and from single valves to complex unit systems.

We perform extensive R&D activities using sophisticated testing and analysis equipment. This dedication to research underpins our ability to consistently create innovative products with outstanding quality and environmental compatibility.

Superior Reliability Backed by KITZ's Own Testing and Analytic Skills

One of the world's leading valve manufacturers, KITZ Group produces more than 90,000 types of valves for a broad range of applications. All our valves boast outstanding reliability and quality due in large part to testing and analytic technologies that are the most advanced in the industry.

Our testing and analysis equipment allows us to study valves and materials under conditions that are exactly the same as in the locations where they will be used by customers. We perform these tests repeatedly. Only the valves that meet our stringent standards for dependability are included in the KITZ product lineup.

KITZ is constantly working on new ideas for products and materials by retaining this commitment to both basic and applied research.

KITZ Corporation R&D Activities

Valves must be engineered to meet the demands of a broad spectrum of applicationsKITZ Corporation R&D activities focus on three vital goals: (1) meeting the manifold needs of user industries, (2) continually upgrading quality and reliability of KITZ products, and (3) heightening the efficiency of the Company's entire operations.

Ongoing R&D projects include developing new basic materials for valve production and designing valves with higher pressure tolerances and larger diameters. The pressure rating of KITZ valves now includes ANSI Classes 1500 and 2500 for extremely high to low temperatures. Beyond standard-size valves, which range to 36 inches in diameter, the company also manufactures custom-made valves with diameters of up to 60 inches.

As part of its goal of becoming the most versatile manufacturer in Japan's general flow control industry, KITZ is working hard to expand its product range. Among our new products are actuator driven valves for computerized plant process control and valves for use in instrumentation, sanitation, and agriculture. In the past five years the Company has also steadily reinforced its production lines for industrial butterfly valves, which have won increasing demand worldwide.

To upgrade product quality and reliability, KITZ's laboratory tests ensure that all its valves meet or exceed the standards set by the world's recognized industrial codes, such as the ISO, ANSI, API, BS, DIN, and JIS. The company's R&D efforts also encompass study of flow dynamics, knowledge of which is vital to the design of new valves. In 1989, to strengthen its sophisticated engineering research of flow dynamics, KITZ established a new laboratory at its Ina Plant. This is one of the very few hydrodynamics laboratories established by valve manufacturers in Japan.

Valves must be engineered to meet the demands of a broad spectrum of applications. Designs need to match the material, whether water, gas, oil or another substance, that is to be controlled. Temperature, pressure, control systems and other factors are also key considerations. With a diverse assortment of products, KITZ Corporation is able to meet every customer need involving valves.
