Safety double valve - メーカー・企業と製品の一覧 | イプロス

[Data] 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 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.
