Proposal for Challenges of High-Temperature Conditions in Solid Material Supply: Case Study Collection *Currently Available for Free*

Proposal for Challenges of High-Temperature Conditions in Solid Material Supply: Case Study Collection *Currently Available for Free*

A must-see for semiconductor material manufacturers! We are presenting examples of proposals addressing the challenges of high-temperature conditions in solid material supply.

We are using all-metal valves in a supply process at 250℃, but we are dissatisfied with their durability. In a supply process at 200℃, we are using valves that cannot have their seats replaced, which means we have to replace the valves, leading to increased running costs. We are using valves rated for 200℃, but the drive components cannot withstand high temperatures, so we are only heating the body. The heat from the heater mounted on the body is dissipating from the drive side, and we are struggling with this issue... Do you have similar concerns? KITZ SCT offers comprehensive solutions for flow path issues. If you have any specific cases you are interested in, please contact us via Ipros or our company website.

Electromagnetic Diaphragm Valve ED-V50 Series

Electromagnetic Diaphragm Valve ED-V50 Series

A diaphragm (fluororesin-based, PTFE) is used for the upper seal of the liquid connection part.

The electromagnetic diaphragm valve ED-V50 series has liquid material inlet and outlet ports that are M6. Since a diaphragm (fluororesin-based, PTFE) is used for the upper seal of the liquid contact part, there is no leakage of liquid materials into the drive body. Depending on the nature of the liquid, all fittings, tubes, and needles in contact with the liquid can be made of resin or Teflon materials. The materials in contact with the fluid (liquid contact materials) are made of highly corrosion-resistant PCTFE and PTFE, making it suitable for a wide range of fluids. For more details, please contact us or refer to the catalog.

Ultra-lightweight and compact type diaphragm valve, DVF (Open/Close-kun)

Ultra-lightweight and compact type diaphragm valve, DVF (Open/Close-kun)

Design tailored for specific uses achieves overwhelming weight reduction! Approximately 1/2 the weight (compared to conventional models)!

The "DVF (Open/Close-kun)" is a valve-integrated fitting born from the innovative idea of "giving fittings a valve function." While maintaining the same structure and functionality as the conventional metal diaphragm valve DVF series, it achieves an overwhelming weight reduction of 50% compared to traditional products. It is suitable for high vacuum, high durability applications and can be used in manufacturing lines that require ultra-pure fluids, flammable, or toxic fluids (such as in the semiconductor field, bulk gas, and high-purity gas applications). It is designed for small diameter piping. *For more details, please download the materials or feel free to contact us.*

Electromagnetic Diaphragm Valve ED-V50 Series

Electromagnetic Diaphragm Valve ED-V50 Series

There is no liquid material wrapping around the drive body (drive part).

In the electromagnetic diaphragm valve ED-V50 series, the inlet and outlet for liquid materials are M6. The upper seal of the wetted part uses a diaphragm (fluororesin-based, PTFE), preventing liquid materials from flowing into the drive body. Depending on the liquid content, all wetted fittings, tubes, and needles can be piped using resin or Teflon materials. For the materials that come into contact with the fluid (wetted part materials), highly corrosion-resistant PCTFE and PTFE are used, making it suitable for a wide range of fluids. For more details, please contact us or refer to the catalog.
