[Question] What is the recommended torque for maintenance of a diaphragm valve? [Answer] The tightening torque varies depending on the size and material of the diaphragm. If the tightening is too strong, it can deform the diaphragm or cause it to wear out more easily, leading to leaks. Please download the diaphragm valve torque table for reference! *The values listed in the data are reference values for appropriate torque to preserve the diaphragm.*

Q: Is it possible to sterilize and clean the piping of a manual diaphragm valve at 120°C (SIP/CIP)? Additionally, what is the expected temperature rise at the handle during this process? A: The maximum temperature for steam sterilization is 150°C, and the temperature rise at the handle is approximately 45°C, so it can be safely operated even after the sterilization process. *Please inquire as the heat resistance duration may vary depending on the diaphragm. *For autoclave processing, some products may not be compatible, so please inquire.

"Industrial wastewater treatment" is a process for treating or reusing wastewater generated in industries such as food production, brewing, and chemical manufacturing. The purposes of wastewater treatment are varied, including recycling back to the process, supplying water to receiving tanks, and discharging into sewage systems. In manufacturing, some companies emphasize the closure of various manufacturing processes and the reuse of raw materials. The reuse of raw materials not only reduces environmental impact but also significantly contributes to cost reduction. With extensive experience and a wide range of products, our company consistently provides appropriate technologies and products for diverse applications. [Main Treatment Methods] ■ Wastewater treatment in the solar cell wafer manufacturing process ■ Wastewater treatment in plating processes ■ Wastewater treatment in the food industry, etc.
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.
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.
Proposal for the optimal valve for an extremely complex manufacturing process.
"Pure water and ultrapure water" are necessary in the pharmaceutical and biotechnology industries for the production of pharmaceuticals and materials, as well as in the microelectronics and semiconductor industries. Since pure water significantly affects product quality and manufacturing process efficiency, the plant components are subject to extremely strict requirements. Our company offers diaphragm valves specifically designed for use in ultrapure water treatment and supply equipment, as well as process equipment.
Proposal for supply valve for process water.
The power plant has various process water circuits, and corresponding purification treatment of raw water and pre-treatment for discharging wastewater into the sewer are necessary. Our company provides valves for supplying water to various treatment processes.
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.
