Cast Carbon Steel Valves

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.

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.

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.

“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.

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.

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.
