Hydraulic Cut-off & Load Holding Safety Valve "HBH Series"

Hydraulic Cut-off & Load Holding Safety Valve "HBH Series"

Redundant valve for external control! Designed for applications where safe load retention is essential!

We would like to introduce our hydraulic shut-off and load-holding safety valve, the 'HBH Series.' In the event of a loss of supply pressure and/or power, it stops and holds the movement of the cylinder. By introducing a hydraulic double valve, we not only improve machine safety but also standardize hydraulic safety solutions, simplifying complex circuit designs. The test port included in the double valve allows for quicker troubleshooting and reduces machine downtime, enabling improved operational efficiency and cost savings. 【Features】 ■ Maximum flow rate: 145 gal/min (549 l/min) ■ Two body sizes: (D52, D32) ■ Port sizes: 1 1/2” and 2”, Code 62 Flange *For more details, please refer to the PDF document or feel free to contact us.

[Information] Approaching "unexpected" without sound...

[Information] Approaching "unexpected" without sound...

Please be sure to include oil and pneumatic pressure in the machinery safety cycle. The solenoid valve is part of the safety-related parts of the control system (SRP/CS).

Scene content: While the machine operator opened the interlocked door to change the mold and was cleaning the mold, the moving mold, which was supposed to stop due to the interlock mechanism, slowly and quietly moved towards him without him noticing. By the time the machine operator realized this... as a result, he suffered severe injuries, having a part of his body caught and severed by the mold.

Data "Hydraulic Shut-off & Tank Return Safety Valve System HBB Series"

Data "Hydraulic Shut-off & Tank Return Safety Valve System HBB Series"

Notice, Warning, Standard Guarantee, etc.! HBB Series Valve System Integration Guide

This document is an integration guide focusing on the "HBB Series Valve System." It includes information on "tank return flow and tank return flow during failure," as well as "valve operation" and "monitoring of operational failures." This series is utilized for safe hydraulic shutdown and tank return functions, and it outputs feedback to an external monitoring safety control system using a PNP inductive position switch. [Contents (partial)] ■ Introduction ■ Pulse Testing ■ Tank Return Flow and Tank Return Flow During Failure ■ HBB Wiring (Pin Configuration) ■ Pilot Supply Conversion *For more details, please refer to the PDF document or feel free to contact us.

Hydraulic Cut-off & Tank Return Safety Valve "HBB Series"

Hydraulic Cut-off & Tank Return Safety Valve "HBB Series"

The pipe sizes are compatible with 1/2” to 1-1/4”! Redundant valve system with external monitoring specifications.

The "HBB Series" is a redundant 3/2 valve system for external control that meets the needs and requirements for safe hydraulic shut-off and tank return for machines equipped with hydraulic control. By introducing a hydraulic double valve, not only is machine safety improved, but it also standardizes hydraulic safety solutions and simplifies complex circuit designs. The test port included in the double valve allows for quicker troubleshooting and reduces machine downtime, enabling improved operational efficiency and cost savings. 【Features】 ■ Shuts off hydraulic supply pressure and returns secondary side pressure to the tank ■ Equipped with a relief valve on the inlet side ■ Maximum flow rate is 50 gpm (189 l/min) *For more details, please refer to the PDF document or feel free to contact us.

[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.
