Ceramic lining diaphragm valve "480(04) type"

Ceramic lining diaphragm valve "480(04) type"

Introduction to porcelain lining products with excellent resistance to corrosion and chemicals.

The "480(04) type" is a diaphragm valve made of porcelain lining that excels in corrosion and chemical resistance. It does not experience the permeation of chemical liquids, which can be a concern under certain conditions with fluororesin lining or rubber lining. Additionally, it is suitable not only as a corrosion-resistant valve for strong acid fluids but also for highly permeable fluids such as hydrochloric acid and phosphorus trichloride. 【Features】 ■ Does not experience the permeation of chemical liquids, which can be a concern under certain conditions with fluororesin lining or rubber lining. ■ Suitable not only as a corrosion-resistant valve for strong acid fluids but also for highly permeable fluids such as hydrochloric acid and phosphorus trichloride. ■ Base material: FCD-S, Lining: Porcelain *For more details, please refer to the PDF materials or feel free to contact us.

Rapid opening and closing handle - Bio-clean diaphragm valve

Rapid opening and closing handle - Bio-clean diaphragm valve

Easy with 90-degree operation! Prevents over-tightening and damage! We solve concerns like "I'm worried if it's securely tightened..."

The "BQL400NB model" is a rapid-opening and closing type handle diaphragm valve from BioClean. While the standard handle version requires about 5 turns of operation (for DN50), the rapid-opening and closing handle allows for a very simple operation of just 【opening and closing by 90 degrees】. The position of the handle makes it clear to see the valve's open and close status even from a distance. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable sealing performance of the 90-degree rotating lever handle. 【We solve the following problems!】 ■ The opening and closing torque is excessive. → It can be reduced, greatly contributing to labor savings. ■ I want to check the open and close status from a distance. → The handle position clearly shows the valve's open and close status even from afar. ■ The valve is damaged due to over-tightening. → Only the minimum necessary operation is required. This prevents damage and extends lifespan. *For more details, please refer to the PDF materials or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)
