Building and Construction

Bronze and Brass Valves

Wide range of bronze and brass valves to meet customer needs. Through valve manufacturing pursuing high quality, both production volume and delivery results, KITZ group is well known as the top brand in all over the world.

Cast Iron Valves

Cast iron valves are common valves that are widely used in various applications of equipment used in building equipment, as well as in plants and ancillary equipment in various factories.

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.

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.

Aluminum Butterfly valves (XJ series)

This is a KITZ' s standard butterfly valve. Long neck, short neck and necklace are available for a wide range of piping. Stainless steel discs and EPDM rubber sheets are available for various types of line-fluids without concern for corrosion.

Ductile cast iron Butterfly valves (DJ series)

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

Ductile cast iron High rangeability Butterfly valves (HRDJ Series)

Arrangeability 160:1 flow rate control with multi-control of minute flow rate and tight shut when fully closed.

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.

Grooved End Butterfly valve

2“ to 6” ( Lever operated)  and 2“ to 12” (Gear operated) are line up. Maximum Operating Pressure is 300PSI. (This product has a limited sales area. Please contact to your local KITZ sales)

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.

PN Rating valve

PN10, PN20, PN25 are line up.
