[New] Wear-type diaphragm valve "SWD/MWD Series"

[New] Wear-type diaphragm valve "SWD/MWD Series"

The manual type "MWD series" is newly launched! Pursuing cleanliness to the utmost limit. A wide variety of pipe diameters is now available, making it even easier to use!

The manual type "MWD series" has been newly added to the lineup of wear-type diaphragm valves that consolidate CKD's valve technology. There is now a wide variety of piping diameters available, allowing for selection according to the usage scenes of various devices. ▼ Three points pursued for cleanliness and ease of use 《1》Clean ○ Achieves high aseptic properties Eliminating the pocket area between the diaphragm and the body ensures no liquid residue, keeping the valve clean. ○ High replaceability reduces cleaning time The dead space where liquid can stagnate is minimized, allowing for thorough cleaning of every corner of the flow path. 《2》Maintenance ○ Reduces maintenance time By optimizing the diaphragm, it can be easily replaced, and a unique mechanism ensures accurate positioning of the diaphragm. This design allows for easy assembly and ensures reliable sealing, thus reducing maintenance time. 《3》Compact ○ Increases design development flexibility for devices (SWD) Thanks to unique technology, the actuator is compact relative to the valve diameter. ○ Provides ample maintenance space (MWD) The adoption of a manual handle allows for sufficient space within the device, making valve operation easy.

Application example: "Industrial wastewater treatment"

Application example: "Industrial wastewater treatment"

We propose components that match various conditions, such as fluid and processing processes.

"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.

Application example: "Drinking Water Treatment: Ultrafiltration (UF)"

Application example: "Drinking Water Treatment: Ultrafiltration (UF)"

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.

Application example: "Wastewater treatment in the manufacturing process of solar cell wafers."

Application example: "Wastewater treatment in the manufacturing process of solar cell wafers."

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.

Application example: "Wastewater treatment in the plating process"

Application example: "Wastewater treatment in the plating process"

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.

Application Example: "Wastewater Treatment in the Food Industry"

Application Example: "Wastewater Treatment in the Food Industry"

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.
