Valve Products

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 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 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 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.

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.

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, 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.

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

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.

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.

A wide range of KITZ Group valves are used in the construction of high-rise office buildings, hotels, public facilities, homes and other facilities among many of the construction facilities, including air conditioning equipment, heat exchange piping for heat source equipment, hot water supply equipment.

The KITZ Group’s valves, equipped with actuators, provide a wide range of materials, valve types, and automation of production, are used to supply fluids and gases to machinery and equipment production facilities and semiconductor production facilities used in production lines and processing lines.

The KITZ Group's valves are widely used not only in KITZ brand cast steel valves, which have a long track record in petroleum refining and chemical complexes, but also in special applications such as stainless steel, PFAs and PTFE lined ball valves, which are highly resistant to heat and chemicals. In addition, the KITZ Group's trunnion-type ball valves and all-weld-type forged steel ball valves are widely used in natural gas conveyance facilities and pipelines, which are important energy infrastructures, as well as in gas delivery facilities in gas-fired power stations.

For more 70 years, KITZ strive to develop our advanced technologies for creating the future. We develop hydrogen valves with advanced technology for both high-pressure and extreme cryogenic situation. We contribute to the realization of a carbon-neutral society around the world with our outstanding technology.

The demand of Electronics chemicals, Semiconductors materials, Pure water/ultra-pure water, pharmaceutical row materials is increasing in each market sector KITZ will contribute to the process facility of producing those material.

KITZ Group products are also used for valves and fittings that can be used in the semiconductor manufacturing process.

KITZ Group companies provide industrial precision filters using fluid separation technology using hollow fiber membranes for companies and water purifiers for households.

The origin of ”valve” can be traced back to the wooden cock excavated from the ancient Egyptian ruins around 1000 BC. In the ancient Roman period, a water pipe was laid in the aristocracy’s house, and a bronze cock was attached to the outlet. In this way, metallic valve has been in practical use for more than 2000 years.
We would like you to know, pay attention to, and be familiar with valve, which has a long history and is active in a wide range of fields, from home to business.

Various Calculation Tools are available for practical use.
Unit Conversion : Absolute pressure and gauge pressure can be converted in the pressure unit. Gas flow rate can be converted between the actual flow rate and normal flow rate.
Viscosity and kinematic viscosity can be converted in units of viscosity.
PT Rating Interpolation Calculation : By pressure and temperature, value between two points can be calculated by linear interpolation.
Calculating Cv Value by using Simple Formula : You can calculate Cv (Flow Coefficient) for the fluid condition entered for the liquid, gas, and steam.
Flow Rate Calculation : Velocity can be calculated from the flow rate. And flow rate can be calculated from velocity.
