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.

basic information
Points on Labor Safety/Machine Safety The "safety-related parts/control system (SPR/CS)" of the control system begins where safety-related input signals are generated and ends with the output of power control elements (such as solenoid valves). Therefore, a risk assessment that includes solenoid valves is necessary.

The HBB series is a high-control reliability hydraulic control valve classified as Category 4, PL "e" (currently obtaining third-party certification). Scene Content: 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 meet the category/performance level corresponding to this high safety requirement. The introduced valve is a highly reliable, two-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. Labor Safety/Machine Safety Points: The safety-related parts of the control system (safety-related parts/control system: SPR/CS) begin where safety-related input signals are generated and end with the output of the power control element (for example, solenoid valves). Therefore, a risk assessment that includes solenoid valves is necessary.
