Ductile Valves

Ductile valves have a wide operating pressure and temperature range and are more economical than cast steel stainless steel valves. KITZ group standardizes ductile valves used in water, air, gas, oil, and other applications.

Stainless & high alloy steel valves

Stainless steel valves are durable and have traditionally been used in petrochemical and chemical processes. This material is particularly suitable for valves used in processes where fluids reach high/low temperatures. It also complies with standards such as JIS, ANSI/ASME, API, etc.

Cast Carbon Steel Valves

Valves made of cast steel are suitable materials for valves used in high temperature ranges. In addition, for Kitz cast steel valves, body/bonnet materials and trim materials can be selected according to their intended use and operating temperature/pressure.

Corrosion resistant and Special materials

The KITZ Group's valves, which also have casting processes at their own plants, are compatible with a variety of materials. It has materials such as bronze, brass, cast steel, cast iron, ductile cast iron, cast iron lining, stainless steel, and special alloy steel, so it can provide proper valves for corrosion resistance against various fluids, durability, and high temperature range.

Ball Valves

Ball valves, one of KITZ's main products, offer a lineup of valves compatible with a variety of materials. We also produce metal seats that support special lines and can handle operating temperatures up to 500°C, as well as Λ (lambda) port valves that can be closed and controlled to accommodate slurry fluids. We apply standards such as ANSI/ASME and API,MSS,ISO,DIN,JIS to supply worldwide.

Butterfly Valves

KITZ offers a variety of butterfly valves in combination with body materials and seats to meet customer needs.

Gate, Globe, Check Valves and Strainer

Various valves are available in a wide range of applications, including gate valves, which can be manufactured in a wide variety of sizes, have a wide range of material options, and have a wide range of pressure and temperature response ranges, globe valves, which have a shorter opening and closing time than gate valves and can change flow characteristics with a jisk shape, check valves that constantly maintain fluid flow in a constant direction and prevent backflow, and strainers for removing foreign matter from fluids. Information on gate valves, globe valves, and check valves can be found in most catalogs for each material.

Actuated Valves

Electric open/close operation actuators that can be mounted on ball valves and butterfly valves are available. The actuator body is made of aluminum die-cast and the reduction gear is made of planetary gears, making it lighter and more compact.

PFA-lined Ball valves (UTBLN Series)

PFA exhibits excellent properties as a lining material, while having heat and chemical resistance and mechanical properties equal to or higher than those of PTFE.

Floating type Ball valves (TDZ series)

This floating ball valve complies with international standards. Completely compliant with ISO17292, API608. Has the high performance required for severe service of the plant process. The mounting dimensions of the drive are ISO 5211 and CAPI and are compatible with drive units worldwide. Compliant with CE-mark based on PED 2014/68/EU.

Floating type ball valve (General flange type)

Floating type ball valve with flange type connection. A wide variety of materials are available depending on the application. It is equipped with an anti-static, stem pop-out, locking device, etc.

Λ port ball valve

This valve is structured so that the edges of the Λ characters are formed by the squeegee, and the flow rate is adjusted at the intermediate opening, and foreign matter in the liquid can be cut off while closing it by adopting a metal seat. Suitable for controlling special fluids such as paper, pulp, slurry, clay bodies, etc.

“Filltite®” Special seat ball valves for high temperature

Specially seats with high proportions of carbon-based fillers in PTFE to improve heat resistance and wear resistance. Even at temperatures as high as 300°C, it exhibits excellent operability, durability, chemical resistance, and sealing performance with little permanent deformation.

Carbotite seats and ball valves for high temperatures

Carbotite Seal Ball Valves are ball valves that develop carbon for use in ball seats, and are capable of withstanding a maximum operating temperature of 500°C.

Stainless steel/carbon steel metaball valves

High sealing performance has been realized by high true sphere machining of the bar sphere and lapping of the seat surface. Can handle powders, slurries, viscous fluids, and high-temperature fluids that are difficult to handle with soft seat.

Ball Valves for Low Temperature services

-46℃ for the TDZ series of carbon steels. For the stainless-steel UTDZ series. Compatible with low temperatures down to -104°C.

Ball seats

The HYPATITE® PTFE is a seat for ball valves developed by KITZ.

Trunnion mounted ball valves (for pipeline)

This is an industrial trunnion ball valve with a three-pace structure. Covers ASME, API standard.

Ductile cast iron Butterfly valves (DJ series)

Our extensive product lineup meets diverse needs. The functions required of butterfly valves were thoroughly pursued.

Double eccentric Butterfly valves (HB series)

This valve has a stable sealing property due to its unique sheet shape and material, and can be closed by both forward flow and reverse flow with a RPTFE seat ring to accommodate a variety of fluids.

Double eccentric stainless steel with PTFE seat Butterfly valves (UB series)

This butterfly valve uses stainless steel at the main part and PTFE with excellent chemical resistance at the seat.

High Performance Butterfly valve

*Product for the limited sales area. Please contact to your KITZ local sales.

Automatic valve with pneumatic actuator (B, F series)

This is connected to industrial compressed air piping for use in processes such as petrochemicals, chemicals, and chemicals. The corresponding valves are ball valves and butterfly valves. Actuator models are B, BS, BSW, 3B, FA and FAS type.

Electric actuators for Butterfly and Ball valves – KELMO EX Series

The EX series is an actuator for electric opening and closing operations mounted on ball valves and butterfly valves. Aluminum die-cast castings are used for the actuator body, and planetary gears are used for the reduction gears.

Actuator driven Compact Ball Valves

Bronze, brass and stainless steel valves with electric and pneumatic actuators are available.

Guidance of CE/UKCA marked products

The guidance is introducing how to express the CE/UKCA marking issue on KITZ products.

LNG

Liquefied Natural Gas―LNG (Liquefied Natural Gas), which has been in the spotlight in recent years as a safe and environmentally friendly energy, contributes to a low-carbon society and contributes to the control of global warming because it generates less carbon dioxide when burned than coal or oil. KITZ is expanding its contribution to society by developing Cryogenic valves (-196°C) for LNG plants and LNG receiving terminals, and supplying valves to LNG plants worldwide from its experience in supplying Cryogenic valves to many LNG receiving terminals in Japan.

Cryogenic Valves

KITZ offers stainless steel and carbon steel gate, globe, check , and ball valves for processing, storage, shipment, and distribution of ethylene, LPG(Liquefied Petroleum Gas) , LNG (Liquefied Natural Gas) and other low-temperature or cryogenic fluids, down to -196 ℃（-321°F).
