Globe valve

Globe valve

By changing the shape of the valve body, it can also be used for control operations to adjust the flow rate!

A "globe valve" has a partition inside the valve body, which presses the valve body against the seat surface of the partition to stop the flow of fluid. Since the flow direction changes in an S-shape within the body, the pressure loss is greater compared to other valves. However, by changing the shape of the valve body, it can also be used for control operations to adjust the flow rate. 【Features】 ■ Stops the flow of fluid by pressing the valve body against the seat surface of the partition inside the valve body ■ The flow direction changes in an S-shape within the body ■ Can also be used for control operations to adjust the flow rate *For more details, please refer to the PDF document or feel free to contact us.

Ball valve

Ball valve

A rotary type where the valve rod rotates in place! Easy to fully open and fully close, with excellent operability and visibility.

A "ball valve" is a type of valve that holds a spherical body (the ball) with two seats and operates by rotating 90 degrees to open and close the valve. Due to its rotary (or quarter-turn) structure, where the stem rotates in place, it allows for easy full opening and closing, providing excellent operability and visibility. Additionally, the flow passage inside the valve has almost no irregularities, resulting in extremely low pressure loss. It is widely used in various applications, including "standard bore" and "reduced bore," where the ball hole diameter is gradually smaller than the valve body diameter. Our company also handles valves that meet special requirements, such as high-pressure gas certified valves and oil-free treated products. 【Features】 ■ Easy full opening and closing ■ Excellent operability and visibility ■ Almost no irregularities in the flow passage, resulting in extremely low pressure loss *For more details, please refer to the PDF materials or feel free to contact us.

Data: Capital Investment from the Perspective of Company Safety

Data: Capital Investment from the Perspective of Company Safety

I would be happy if this helps you understand the basic structure of a balance sheet!

When considering the introduction of new equipment, what criteria should be used for judgment? While it is important to assess profitability through break-even analysis for each product, it is also crucial to make judgments from a safety perspective, in conjunction with the company's financial situation. This document first explains the structure of the balance sheet, then discusses the characteristics of the manufacturing industry's balance sheet, and finally describes the criteria for introducing new equipment, namely the "fixed ratio" and "fixed long-term suitability ratio." [Contents] ■ Introduction ■ Structure of the Balance Sheet ■ Balance Sheet of the Manufacturing Industry ■ Fixed Ratio ■ Fixed Long-Term Suitability Ratio *For more details, please refer to the PDF document or feel free to contact us.

Proposal Case Collection

Proposal Case Collection

We propose a specially shaped needle valve that balances quality and cost! We will introduce many case studies.

Matsui Manufacturing is an expert in non-ferrous metal processing. We propose high-quality, high-value-added products that combine forged products made of copper, brass, and aluminum, machining, pipe bending, and brazing. In this document, we introduce several case studies regarding development, quality improvement, and cost reduction. [Some of the content (issues)] ■ We were considering a ball valve for a new product, but the costs did not match. ■ We want to add a safety valve function to the drainage valve to increase its added value. ■ We were using many commercially available copper pipe fittings, which resulted in high material costs. ■ Cutting from aluminum square bars led to high material and machining costs. ■ The yield of brazing in the subsequent process for machined products was poor. *For more details, please refer to the PDF document or feel free to contact us.

[Data] What is an efficient factory? (Improving productivity and ROE) (Free download)

"The productivity of the factory" and the management indicator "ROE" are actually deeply connected! A must-see for team leaders who want to understand the management perspective!

"We need to improve the productivity of the factory." "Improving ROE is our company's challenge." When we talk about "productivity," we refer to factory matters, and when we mention "ROE," it is something the management discusses, which may seem to have no direct relationship at first glance. However, there is a close relationship between the two. Let's specifically examine the relationship between the two through the example of robotization in the production line.

[Data] Usable Excel for Manufacturing Sites (How to Check for Delivery Delays) Free Download

"I want to easily check if there are any delays in delivery." "I want to easily check if there are any products close to the deadline." If you are such a person, please read on!

It is, of course, something that should not happen to have delays in delivery. However, I believe that due to rush orders or machine conflicts, it is sometimes necessary to adjust delivery dates. In this document, I will explain a simple method to check from the delivery schedule compiled in Excel whether there are any items that are delayed or are likely to be delayed (Excel version: 2019). I hope the content of this document will be helpful to you.

[Data] Free Download of Excel for Manufacturing Sites (SUMIF Edition)

I want to be able to use the SUMIF function. I want to know how it is actually used in the factory. If you are one of those people, please read on!

Excel has various functions, and as you study functions like SUM and IF, you may become captivated by their convenience and want to learn even more functions. On the other hand, there may be those working in the manufacturing industry who feel troubled by not knowing "specifically which functions are used and how they are used." In this document, I would like to explore how one of the Excel functions, SUMIF, can be used in the manufacturing industry, using examples.

[Data] Quality Control Usable in Factories (Scatter Plot) (Free Download)

"I learned a bit about scatter plots, but how are they used in practice?" I will explain using a specific example from the valve assembly process!

When you start studying quality management, you will come across something called the "7 QC Tools." These are (1) check sheets, (2) Pareto charts, (3) cause-and-effect diagrams, (4) graphs, (5) scatter diagrams, (6) histograms, and (7) stratification. In this document, we will explain what a scatter diagram, one of the 7 QC tools, is, along with specific methods for creating it and how to interpret it.
