We propose valves that have obtained certification for drinking water.
"Ultrafiltration (UF)" is an established method for treating drinking water, suitable for obtaining drinking water from various raw water sources. A slight pressure (< 0.1 MPa) is applied to the water to be treated, and it is passed through a permeable membrane with a pore size of approximately 0.01 μm. This allows for the removal of extremely fine particles, suspended matter, pollen, bacteria, and even viruses. Dissolved substances such as hardness salts, minerals, or molecules, as well as low molecular weight substances, pass through the membrane along with the water.
This is a valve specifically designed for use with pure steam (sterilization steam).
Pure steam refers to steam used for sterilization, while ultra-pure steam refers to pure steam used in the pharmaceutical industry. The 555 type is a valve specialized for controlling steam that requires high sterility. The spindle is sealed with a bellows, eliminating concerns about external contamination. In addition to its sanitary properties, it also features the compactness, high flow rate, durability, and good controllability characteristic of angle seat valves.
Proposal for a butterfly valve for the water supply of the ion exchange demineralization system.
"Ion exchange" is a method of treating drinking water that partially deionizes it by passing it through layers of various ion exchange resins. Groundwater can contain high levels of alkaline earth ions, carbonates, and sulfate ions depending on the location. Hard water is a significant issue not only for households but also for trade and industry, and it is necessary to remove the salts that cause hardness from drinking water. Deionization can reduce nitrates, sulfates, bicarbonates (HCO3-), and the calcium and magnesium that cause hard water.
We propose stainless steel butterfly valves for low pressure (below 0.4 MPa).
The treated drinking water is sterilized by far ultraviolet (UVC) irradiation before entering the water supply system. This inactivates any remaining microorganisms in the water and suppresses their proliferation. The ultraviolet device has a stainless steel irradiation chamber, and the ultraviolet lamp is housed in a quartz glass protective tube and incorporated into the reaction chamber.
We propose high-durability plastic valves and sealing materials.
The wastewater treatment process for solar cell wafer manufacturing involves the treatment of wastewater containing various components generated from the processing of used slurry. The wastewater mainly contains oils, acids, alkalis, and heavy metals, and may also contain a significant amount of solids. To dispose of such wastewater in accordance with legal regulations or to discharge it into the sewage system, appropriate pretreatment is necessary. By filtering and neutralizing the raw water and then passing it through a reverse osmosis system, it can be discharged into the sewage system.
Proposal for a valve for neutralizing plating wastewater.
The wastewater treatment process for plating involves the addition of alkaline agents such as caustic soda to wastewater containing metal ions, cyanide, chromium, and salts to separate the metals. Carbonates or sulfides may also be used as precipitating agents. Toxic anions are decomposed through oxidation or reduction.
Providing separation technology for handling highly contaminated wastewater.
"Water treatment in the food industry" is an industrial wastewater treatment process that deals with wastewater containing a high amount of organic matter. In the food industry, wastewater containing a lot of organic matter is generated in every sector. Various methods are required for its treatment, including the separation of fats, de-emulsification, sludge treatment, and neutralization. In the neutralization system, it is necessary to constantly monitor the pH level of the wastewater, and it must be kept within the range of 6.5 to 9.5 before being discharged into the public sewer system. Neutralization is carried out by sending the wastewater into a buffer tank and stirring it.
This is a valve specialized for use with pure steam.
Pure steam refers to sterilization steam, while ultra-pure steam refers to pure steam used in the pharmaceutical industry. The 505 type is a valve specialized for controlling steam that requires high sterility. The spindle is sealed with a bellows, eliminating concerns about external contamination. In addition to its sanitary properties, it also features the compact design, high flow rate, durability, and good controllability characteristic of angle seat valves.

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.

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.
