Ceramic lining diaphragm valve "480(04) type"

Ceramic lining diaphragm valve "480(04) type"

Introduction of 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 acidic 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 acidic 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. (We have English and Chinese versions of the catalog available upon request!)

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! "I'm worried if it's securely tightened..." We solve this kind of concern.

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 valve's open and closed status can be clearly seen from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable closing performance of the 90-degree rotating lever handle. 【We solve the following problems!】 ■ Excessive opening and closing torque → Reduction is possible, greatly contributing to labor savings. ■ Want to check the opening and closing status from a distance → The valve's open and closed status can be clearly seen from a distance based on the handle position. ■ Damage caused by over-tightening the valve → 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.)

Diaphragm valve (Type 400 / Type 500)

Diaphragm valve (Type 400 / Type 500)

A structure that opens and closes the flow path with a flexible diaphragm! We will introduce two types of valve designs.

The product consists of three units: the drive part, diaphragm, and main body. It controls the fluid by pressing the diaphragm against the sealing part of the inner surface of the main body and then releasing it. The wear-type "Model 400" maintains airtightness by ensuring that the diaphragm and the main body's dam are in close contact without gaps, demonstrating high valve seat sealing performance. The materials for the main body and diaphragm are diverse, allowing compatibility with a wide range of fluids. Additionally, the straight-type "Model 500" features a flow path that is nearly linear, resulting in a structure with minimal pressure loss and liquid pooling, making it suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. 【Features】 ■ No leakage to the outside and no contamination of the fluid from outside air ■ Zero valve seat leakage ■ Simple main body shape suitable for lining processing ■ Minimizes liquid pooling and possesses self-cleaning properties ■ Adopts a three-unit system, making disassembly and assembly easy *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 site below.)

Cast iron butterfly valve "C201R type"

Cast iron butterfly valve "C201R type"

High sealing performance achieved with a heart-shaped self-seal! Introducing a long-lasting cast iron butterfly valve.

The "C201R type" features a double eccentric (double off-center) design for the disk's drive axis, and since the disk and seat remain in non-contact until just before fully closed, it is a cast iron butterfly valve with minimal seat wear and a long lifespan. The seat is designed with a centering feature on the contact surface, creating a self-sealing mechanism that generates contact pressure on the disk's sealing surface due to fluid pressure, allowing for efficient sealing from vacuum to high pressure. Additionally, during maintenance, the seat can be easily replaced by simply removing the seat cover. 【Features】 ■ Long lifespan due to double off-center mechanism ■ High sealing performance with centering self-seal ■ Easy maintenance *For more details, please refer to the catalog (P11-P17) 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.)
