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 tightened securely..." We solve this kind of problem.

The "BQL400NB model" is a rapid opening and closing type handle diaphragm valve from BioClean. While the standard handle type requires about 5 rotations for operation (in the case of 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 identified from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. We invite you to try the easy operation and stable sealing performance of the 90-degree rotating lever handle. 【We solve these 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 the 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.)

Check valve (non-return valve)

Check valve (non-return valve)

Introduction of a valve that operates and closes after the reverse flow begins.

Stop valves, such as shut-off valves and ball valves, can fundamentally stop both forward and reverse flow, whereas a "check valve" (non-return valve) only stops "reverse flow." Once reverse flow begins, the valve body operates to stop the flow, so except for some specially structured valves, flow adjustment is generally not possible. Commonly used in building facilities and general piping, there are swing type, lift type, dual plate type, and products with special structures such as Smolensky type and tilting type equipped with "springs" to suppress and improve water hammer, as well as ball type and foot valves. 【Features】 ■ Stops only "reverse flow" ■ The valve body operates to stop the flow after reverse flow begins *For more details, please refer to the PDF materials or feel free to contact us.

[Information] Towards the Efficiency of Inspection Operations

[Information] Towards the Efficiency of Inspection Operations

Introducing things to keep in mind when reviewing purchasing sources! [Free materials available]

The emergence of the internet has significantly changed purchasing operations compared to the past. Now, it is possible to obtain information about various companies while sitting at a desk and to request quotes easily. However, it is quite difficult to determine which companies are truly good just by judging them online. Isn't there a tendency to evaluate primarily based on the most straightforward factor: "price"? This document introduces the impact of changing purchasing sources from "companies with low prices but poor quality" to "companies with relatively high prices but good quality." [Contents] ■ Concerns in inspection operations ■ Identifying hidden costs - Is it enough to only look at the purchase price? - Reviewing processing methods ■ Points to consider when reassessing purchasing sources *For more details, please refer to the PDF document or feel free to contact us.

[Material] How to Create Comfortable Air (Basics of Air Conditioning Design) Free Download

How are the temperature and humidity of the air produced by an air conditioner determined? Let me explain the basics!

Air conditioning units are installed in various places such as your home, workplace, and inside stations and buildings. When the air conditioning is in cooling mode, cold air flows out, and when it is in heating mode, warm air flows out. But what specific temperatures and humidity levels are present in the air that comes out? Additionally, what is the reasoning behind determining those levels? In this document, I would like to briefly explore how to create comfortable air using a tool called the "psychrometric chart." *This document has been created with the aim of providing a simple explanation. For more detailed information, please refer to commercially available books and other resources.*

[Data] Management Accounting for Business Decisions ~ Case 3: Should We Sell Intermediate Goods? ~

[Data] Management Accounting for Business Decisions ~ Case 3: Should We Sell Intermediate Goods? ~

I will explain the points to keep in mind in order to effectively use accounting figures for management decisions!

It is often said that 'business should be considered in terms of numbers.' When it comes to management decisions, the first numbers that come to mind are the financial figures used in accounting (such as sales, manufacturing costs, and gross profit). It would be great if we could make the right decisions using these numbers, but if we misuse them, we can end up making unexpected mistakes. In this document, I would like to introduce and explain the 'traps of easily misinterpreted numbers.'

[Material] Basic Series on Geometric Tolerances 11 - Contour Tolerance - (Free Download)

"What is 'contour degree'?" This is a document that also mentions usage examples and measurement methods!

When performing turning or milling operations, the workpiece may retain traces of the cutting tool, and due to the effects of distortion or deflection during processing, there may be some deviation from the ideal shape. Geometric tolerances are used to indicate how much deviation from the ideal shape is acceptable. By understanding geometric tolerances, one can discern the designer's intentions behind the drawings. This also clarifies how to proceed with processing and inspection based on specific references. This document explains a type of geometric tolerance known as "contour tolerance." It discusses both "line contour tolerance" and "surface contour tolerance," as well as how to differentiate between the two.

[Material] Basic Series of Geometric Tolerances 12 - Circumference and Total Runout - (Free Download)

"What is 'circumferential deviation and total deviation'?" This is a document that also mentions usage examples and measurement methods!

When performing turning or milling operations, traces of the cutting tool may remain on the workpiece, and due to the effects of distortion or deflection during processing, there may be some deviation from the ideal shape. Geometric tolerances are used to indicate how much deviation is acceptable between the ideal shape and the actual shape. By understanding geometric tolerances, one can discern the designer's intentions behind the drawings. It also clarifies how to establish reference points and conduct processing or inspection. This document explains a type of geometric tolerance known as "circular runout and total runout." It will cover not only the definitions but also the situations in which they are used, as well as the measurement methods.
