Application example: "Production of Purified Water (PW) and Highly Purified Water (HPW)"

Application example: "Production of Purified Water (PW) and Highly Purified Water (HPW)"

Proposal for valves for electric regeneration pure water systems (EDI).

"Highly purified water (HPW)" is generally produced in the final stage of manufacturing by removing particles, bacteria, and pyrogens, and by installing a membrane filtration system to maintain the quality of the purified water. "Purified water (PW)" is produced by combining membrane separation methods and ion exchange methods, while the electric regeneration type pure water device (EDI) combines both of these methods for production. We offer diaphragm valves specifically developed for use in ultra-pure water treatment and supply equipment, as well as process equipment.

Application Example: "Pure Water and Ultra-Pure Water Production: Ultra-Pure Water (UPW)"

Application Example: "Pure Water and Ultra-Pure Water Production: Ultra-Pure Water (UPW)"

Proposal for valves and flow meters for the supply of ultra-pure water (UPW).

Ultra-pure water (UPW) is widely used in the manufacturing processes of semiconductor and solar cell wafers. The abrasives that adhere to the wafer surface are removed during the cleaning process and are washed again with ultra-pure water in the final stage. Cleaning with ultra-pure water is also necessary to remove residues generated during the subsequent etching process. Maintaining the wafer surface clean during such manufacturing processes leads to maximizing power generation efficiency. We offer diaphragm valves specifically developed for the treatment and supply of ultra-pure water, as well as for use in process equipment.

【Q&A】Can the handle of the manual valve be fixed?

【Q&A】Can the handle of the manual valve be fixed?

We will solve your valve problems!

Q: After setting the manual handle to the specified position, it may unintentionally move, causing the opening degree to change. What is a way to prevent such a manual handle from moving? A: The GEMU manual diaphragm valves model 653 and 654 have a specification with a handle lock that can fix the handle in the specified position, allowing for adjustment of the opening degree only when necessary. *There is also an electric specification that uses a solenoid valve for locking, rather than a mechanical one. Please refer to the instruction manual for more details.

How much do I need to turn the handle for it to close? Solved!!

How much do I need to turn the handle for it to close? Solved!!

How much do I need to turn the handle for it to close? Solved!!

Aren't you worried about how much to tighten the handle before it closes, and end up tightening it too much? Over-tightening the handle can lead to damage to the diaphragm that stops the fluid. This product comes standard with a system called "Seal Adjuster," which allows you to adjust the fully closed position of the valve! By using this system, you can achieve: 1. Prevention of diaphragm failure due to over-rotation of the handle 2. Adjustment of flow rate. There is a clear difference in strength between women and muscular men, which affects how much force they can apply to turn the handle. However, by setting the fully closed position, anyone can close the valve at the same position regardless of their strength! Additionally, it can fulfill the desire to adjust the flow rate consistently just by turning the handle. Setting the Seal Adjuster is also very easy!
