![[Data] I have conducted a risk assessment for the final drive machinery!](https://image.www.ipros.com/public/product/image/799/2000504280/IPROS02292288610151789017.jpeg?w=280&h=280)
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 deemed a significant risk. It is necessary to introduce products that correspond to the category/performance level that meets these high safety requirements. 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.
![[Data] Usual press work](https://image.www.ipros.com/public/product/image/53d/2000504291/IPROS31241380955899710191.jpeg?w=280&h=280)
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 are repeatedly opening and closing almost simultaneously. When the power to the valve is turned off and one side does not close (failure), 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 reapplied even when one side is in a failed state. Air leakage occurs from the valve's exhaust port, but this "failure indication" is difficult to notice.
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 was already malfunctioning. 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, so the secondary side air could not be exhausted, and the press did not stop. The operator could face a "pinching accident."
Valves with monitoring devices can detect valve body failures. Operators can focus on their work with peace of mind.
Content of the scene: A valve with a monitoring device performs 1) fault detection, 2) output of fault signals, and 3) prevention of restart when a failure occurs on one side. In particular, 3) ensures that the valve does not operate even if power is supplied during a fault, thereby ensuring the safety of the operator. With monitoring, the operator is freed from checking for air leaks and can focus on more productive tasks.
Compressed air is one of the expensive forms of energy produced by operating a compressor. The majority of it is used in the air blow (cooling) process.
This is a poppet-type solenoid valve with high durability and high responsiveness. By rapidly turning the poppet solenoid valve ON/OFF, it is possible to intermittently blow air (cooling) and significantly reduce the amount of compressed air used. By accurately controlling the frequency (the number of ON/OFF cycles per second) and the duty ratio (the ratio of ON to OFF) electrically, it is possible to maintain sufficient blowing force required for the application while reducing compressed air consumption by more than 50%. Additionally, our poppet valves are not disposable. We sell internal component sets such as O-rings and pistons, so by replacing worn parts, you can continue to use the main unit. The size of the pulse blow valve is wide-ranging, with options available up to super large diameter (65A)!
![[Example] The material activation system continuously feeds the ingredients for pet food.](https://image.www.ipros.com/public/product/image/afd/2000572090/IPROS56245626164917894864.png?w=280&h=280)
Strategically placed in the dry mix container! To flow the processing system efficiently and safely.
For pet food manufacturers, avoiding cross-contamination is central to the manufacturing process. "Bulk material flow issues," such as rat holes, bridging, and other material blockages, reduce the flow of materials through the processing system and increase the likelihood of cross-contamination. In 2018, research was conducted to replace the ineffective material activation system in use at the time with a new system, planning the introduction of "AirSweep." By converting pet food ingredients from vibrators and air hammers to this unit, the processing system has become more efficient and safe in its flow. *For more details, please refer to the PDF materials or feel free to contact us.*

Explaining two frequently asked questions regarding the integration of valves into safety systems!
The typical application of the DM2 series C valve is to shut off the compressed air energy supplied from the air inlet while dissipating the energy on the secondary side of the valve. When safety events occur, such as the opening of guard doors or the operation of emergency stop devices, this valve dissipates the downstream pressure of the system and removes the pneumatic energy. There are two common questions regarding the integration of this valve into safety systems. "Why does the valve not have two feedback switches for monitoring by the safety system?" "How should the downstream pressure be monitored by the safety system?" To answer these two questions, some information about the valve's function is necessary. We provide a detailed explanation in this document, so please take a look. *For more details, please refer to the PDF document or feel free to contact us.*
