【Data】Comparison of the safety of monitor-equipped double valves with other valves.

Achieving safe press processing! Introducing the safety of double valves with monitors.

This document introduces how double valves with monitors ensure safety compared to conventional single valves and double valves without monitors. In the control valves of press machines, by introducing double valves with monitors, accidents that cannot be prevented by workers alone can be avoided, ensuring high safety. With our double valves, monitors can be retrofitted, so if you are using double valves without monitors, please consider upgrading to those with monitors to enhance safety.

[Information] Let's introduce a double valve with a monitor based on European and American standards.

Upgrade your safety management! Introducing the double valve with a monitor.

This document introduces "monitor-equipped double valves" as an example of enhancing safety management standards. The monitor attached to the double valve has the function of detecting malfunctions and preventing restarts. If the press machine operates while malfunctioning, there is a possibility of accidents; however, the monitor can prevent accidents by cutting off the electrical and pneumatic circuits within the double valve. Our company offers a wide range of products that meet global standards, so if you have any concerns about safety, please feel free to consult us.

Is it dangerous to take MTTF at face value? The relationship between MTTF and reliability.

Is it dangerous to take MTTF at face value? The relationship between MTTF and reliability.

The lifespan of a product is a major selection point! Introducing the relationship between product reliability and MTTF.

This document introduces the relationship between product reliability and MTTF (Mean Time to Failure). MTTF is often used as an indicator to understand the lifespan of a product. If the MTTF of a product is known, one can grasp the average lifespan of that product. Additionally, while utilizing MTTF as one of the indicators, it is important to be aware that theoretically, there is approximately a 63% probability of failure occurring before reaching the MTTF.

Understanding the flight method (unofficial) of category-specific architecture.

Introducing a way to understand the flight-style (unofficial) specifications of each category in SO13849-1 architecture!

Among the four items that determine the Performance Level (PL) of ISO13849-1, there is the category (Categories). It is divided into five levels: B, 1, 2, 3, and 4, according to the specified architecture, with the required safety functions becoming stricter at each level. This is a simplified (informal) method to understand the safety levels of the specified architecture. In this document, we will convey a simple way to understand the surface aspects of this safety category using airplanes.

Let's check the laws and regulations to protect the workplace environment!

Let's check what laws and regulations have been established to protect the workplace environment where we work!

This document introduces the "Labor Safety and Health Act," which serves as the foundation for protecting workplace environments. The "Labor Safety and Health Act," established in 1972, aims to ensure the safety and health of workers in the workplace and promote the creation of a comfortable work environment by implementing comprehensive and planned measures to prevent labor accidents. This includes establishing hazard prevention standards, clarifying responsibility systems, and promoting voluntary activities in conjunction with the Labor Standards Act. Additionally, it includes information on the "Labor Accident Prevention Plan," which outlines key areas the government is focusing on to reduce labor accidents.

【Data】It takes more time than expected...

【Data】It takes more time than expected...

The exhaust port diameter of the ROSS high-speed manual pressure relief valve is equal to or larger than that of the inlet and outlet sides, allowing for the discharge of residual pressure at one of the fastest speeds in the industry.

Scene content: A machine maintenance technician performing regular machine maintenance during the Golden Week. Following company rules, they search for the residual pressure relief valve to shut off all power energy to the machine, cut off the supply air, and begin venting the residual pressure air in the piping. With a typical ball valve, it takes much longer than expected to vent all the residual pressure air in the piping. If one approaches the machine with the mindset of "Well, as long as it's mostly vented, it's okay," the compressed air that is still present may suddenly cause the cylinder to move.

[Information] I have conducted a risk assessment for the final drive machinery!

[Information] I have conducted a risk assessment for the final drive machinery!

The HBB series is a high control reliability hydraulic control valve in category 4, PL "e" (currently obtaining third-party certification).

Content of the scene After conducting a risk assessment of the machinery, the failure of the power control element (cylinder control valve) was determined to be a significant risk. It is necessary to introduce products that meet the high safety requirements corresponding to the category/performance level. The introduced valve is a highly reliable, dual-channel redundant valve that ensures power (hydraulic) is reliably cut off even if the hydraulic cylinder control valve fails. In conjunction with the interlock, it cuts off the supply pressure and returns the power (hydraulic) of the moving mold to the tank, allowing the operator to safely perform mold changes.

[Information] Usual press work

[Information] Usual press work

Is it really safe because it has a double valve? It is safer than a single valve, but a double valve only has two valve bodies inside.

Scene content: Inside the double valve, two valve bodies repeatedly open and close almost simultaneously. When one side does not close (failure) after the valve is turned off, the valve body on the functioning side closes, and the secondary side air is exhausted, causing the press to stop. However, the double valve can still operate if power is restored even when one side is malfunctioning. Air leakage occurs from the valve's exhaust port, but this "failure indication" is difficult to notice.

The valve was broken...

The valve was broken...

Do you notice the malfunction? Valves without monitoring devices make it difficult to detect failures. If both valve bodies fail, the press will not stop...

Scene content As usual, the press operation was underway, but one side of the valve had already malfunctioned. The operator continued to operate without noticing the signs of one-sided failure (air leakage from the exhaust port)... When the power to the valve was turned OFF, both valve bodies failed, resulting in none of the valves closing, which meant that secondary air could not be exhausted, and the press would not stop. The operator could face a "pinching accident."
