KITZ Corporation
About KITZ
KITZ Corporation, established in 1951, is one of the world's leading manufacturers of valves, and Japan's largest. Its 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 Japanese 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. With these strategies, KITZ intends to uphold and increase its worldwide reputation for superior performance and reliability of all its products manufactured in Japan and abroad. Product
KITZ Corporation produces a broad range of commercial, residential, and industrial valves. This product line includes Ball, Butterfly, Gate, Globe, and Check valves available in bronze, brass, iron, carbon, stainless, and alloy steel.
All KITZ valves are subjected to rigorous quality checks and extensive testing before leaving the factory. Testing includes compliance with internal quality control for body and seat integrity exceeding applicable recognized industry standards such as MSS, API and ASME.
KITZ global reputation is firmly based on their commitment to the design and manufacture of quality valves. As a wholly owned subsidiary, KITZ Corporation of America provides product and services to our customers throughout the western hemisphere. Commercial & Industrial Valve KITZ Ball Valves are designed with extensive safety considerations. Vented-ball, blow-out-proof stem and prevention of lever misalignment are all standard features that contribute to safe handling and trouble free operation. Lever operation is standard on most of our ball valves; however; Oval Handles, Locking Ovals, Wing Handles, Extended Stems, or Insulated Stem Extensions can be provided. Grounding Devices and Memory Stops are also available. Lower operating torques and smooth operation are benefits of the quality designed into every KITZ ball valve. Bronze and Brass valves are Full Port as standard, with the exception of our Code No. 51 and the 3-Way Ball valves. Third-party approvals from CSA, UL and FM are available on a number of the commercial and plumbing ball valves.
KITZ Butterfly Valves are designed and manufactured to perform in a broad range of applications. DUCTILE Iron is the only body material we offer, allowing our Lug style butterfly valve to be FULL RATED for Bi-Directional DEAD END service. They meet or exceed the design requirements of MSS SP-67 and API 609.
KITZ Bronze Valves are produced on fully automated molding and machining lines. This highly automated process assures consistent precision in manufacturing commercial and industrial valves for various water, oil, gas, and steam applications. Each of our manufacturing facilities utilizes a fully integrated system devoted to all phases of production. From the selection of materials, to the final testing and packaging, every step is subject to rigorous quality control.
KITZ Iron valves are no different. Since the performance of iron valves depends greatly on the quality of the castings, molten iron is carefully controlled through one of the most advanced casting facilities in the industry. KITZ Iron Valves are widely used in building piping systems, water treatment plants and industrial facilities.
Stainless Steel Valves are used in applications where Bronze, Brass, Cast Iron and Carbon Steel cannot withstand highly corrosive medias or atmospheres. KITZ standard 316 stainless steel valves are designed and built to meet those needs. As one of the world's largest stainless steel valve manufacturers, KITZ incorporates the same quality control process in both our commercial and industrial product lines. Product Technology Just-in-Time Production System
In 1987, KITZ upgraded its production system, carefully integrating the just-in-time, or rolling stock system into its operations to increase production efficiency for smaller, more varied customer requirements. The Company is now able to respond to continually changing customer needs and to provide much more versatile and flexible product service.?
Unique In-House Casting System
The uniqueness of our foundry operations is well demonstrated by the molds we prepare for our stainless steel valves, for example. The molds are made of 100% chromite sand, which does not crack or deform even after direct contact with steel heated to 1350¡ãC. Compared with the silica sand used elsewhere in the industry, the shorter cooling time and greater decarburization effect of the chromite sand used by KITZ result in castings with a much smoother surface finish and better corrosion resistance. Transfer Machine Technology
KITZ is one of the few manufacturers to take advantage of transfer line technology in machining valve components. Our transfer lines are so precisely calibrated that any dimensional inaccuracy in the castings is rendered inconceivable. Our assembly lines are equally sensitive to dimensional inaccuracies. Hydrostatic and pneumatic tests are incorporated at the last stage of the assembly process, and none of our automatically assembled valves leaves the assembly line without meeting the requirements of API 598 or any other applicable test standards. Research & Development
KITZ 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.
