We propose valves that are compatible with the supply of chemical products.
In boiler equipment, corrosion and sedimentation caused by dissolved salts in water are problematic. To avoid these issues, various requirements are imposed on the quality of boiler water based on the operating methods and structure of the steam generation equipment. Our company provides valves for supplying water and chemicals to boilers.
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.
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.
We propose valves that are optimal for handling chemical substances.
In many high-tech fields, the purity of process fluids determines the quality and quantity of the products. GEMÜ products are responsible for fluid control in cleaning, coating, etching, and filling processes within production facilities. GEMÜ's strengths in the chemical supply sector lie in its extensive lineup that caters to various applications and its high durability that does not compromise fluid purity.
We propose valves that are optimal for handling chemical liquids.
The wet process refers to the stage in the production system where liquids, particularly chemical liquids, are applied, and it is a core process in semiconductor manufacturing. GEMÜ products are made with wetted parts of PTFE or PFA, providing high chemical resistance that is unaffected by corrosive chemicals. Additionally, they offer added value such as space-saving, flexible and compact design, as well as high flow capacity with minimized pressure loss.
We propose valves compatible with various purities of water.
In the high-tech industry, the final quality of products is determined by the purity of water known as ultra-pure water or pure water. GEMÜ's high-purity diaphragm valves have been developed for the processing, transportation, and supply of ultra-pure water, as well as for use in process lines. Additionally, not limited to the high-tech industry, GEMÜ offers a wide range of products for equipment related to water treatment.
Chemical-resistant valves for solar cell manufacturing processes.
The manufacturing of solar cells also incorporates a wet process, where the chemical resistance of the components is prioritized over maintaining the purity of the fluids. GEMÜ offers a wide range of PFA, PVDF, and PP components.
A product range capable of supplying and transporting chemical products on a general industrial production scale.
In general industrial fields that use large amounts of chemical fluids, various fluoropolymer components from GEMÜ can be used. Valves are available in sizes up to 100A (4').
A range of PFA products with excellent chemical resistance and cost performance.
In the semiconductor industry, lines that use ultra-high purity solvents have advanced requirements in terms of both chemical resistance and cost. GEMÜ offers a wide range of PFA products that combine high flow capacity with excellent economic efficiency.
A product group suitable for the treatment of deionized water.
This application uses GEMÜ's PVDF and PP valves. High-quality materials and a metal-free structure are suitable for handling deionized water.

Utility valve suitable for steam and liquids, equipped with various features such as high durability, easy maintenance, prevention of water hammer, and the role of a check valve.
The "angle seat valve" combines all of these features. Common disadvantages of widely used valves include: - In the case of ball valves, with each opening and closing, the material between the ball (valve body) and the valve body wears down. As wear progresses, it will leak from that area and no longer function as a valve. - In the case of solenoid valves, the flow path is complex and the pressure loss is significant, so while the solenoid valve itself is compact, it requires a large force from the pump. The "angle seat valve" compensates for these disadvantages and possesses characteristics suitable for steam and liquid processes, making it possible to achieve applications closer to the ideal.
