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 safely holding a load 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 reduction of machine downtime, enabling improved operational efficiency and cost savings. 【Features】 ■ Maximum flow rate is 145 gal/min (549 l/min) ■ Two body sizes available (D52, D32) ■ Port sizes are 1 1/2” and 2”, Code 62 Flange *For more details, please refer to the PDF document or feel free to contact us.

Improved safety and machine work efficiency! What is "Single Point Lockout"?

Improved safety and machine work efficiency! What is "Single Point Lockout"?

Consolidate multiple lockout points into one to ensure safety and efficiency simultaneously! This is an introductory document about single point lockout.

This document introduces single point lockout as an effective means to achieve both safety and cost reduction. Single point lockout consolidates multiple lockout points, which often span several locations, into one, allowing all machines to be stopped with a single lockout/tagout. With this method, lockout/tagout can be completed with minimal time and effort, preventing workers from skipping the process. We encourage you to consider implementing this to enhance safety and efficiency in machine operations.

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

[Information] Approaching "unexpectedly" 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 a machine operator was opening a door with an interlock to change a 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, he had already suffered serious injuries, resulting in a part of his body being caught and severed by the mold.

[Data] Ensuring safety through the redundant structure of 2-channel systems.

[Data] Ensuring safety through the redundant structure of 2-channel systems.

The HBB (Hydraulic Shut-off & Tank Return Valve) from ROSS is designed to handle not only a single failure (such as a failure of one side of the valve body) but also...

Scene content: A solenoid valve (power control element) was installed to ensure safety through a redundant structure and cross-checking (mutual monitoring) in the two channels. Even in a situation where one valve body was broken and could not shut off the hydraulic pressure, the other valve body operated normally to shut off the hydraulic pressure and return it to the tank, allowing the operator to safely complete the mold exchange.

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

Data "Hydraulic Cut-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 shut-off and tank return functions, using a guided position switch (PNP) to output feedback to an external monitoring safety control system.

[Useful Materials for Machine Safety] Methods for Risk Assessment and Examples of Judgment Criteria

[Useful Materials for Machine Safety] Methods for Risk Assessment and Examples of Judgment Criteria

We will introduce a new risk assessment method for conducting risk assessments on machines/equipment that use oil pneumatic energy!

【Useful Materials for Machine Safety】Methods of Risk Assessment and Examples of Judgment Criteria ★ "Machine safety" refers to the practice of anticipating potential accidents that may occur when using machinery and taking measures to ensure safety in order to avoid such accidents. ★ ~ The Importance of Risk Assessment for Pneumatic and Hydraulic Equipment ~ To ensure the safety of pneumatic and hydraulic machinery, risk assessment is the first step! This document introduces points to consider when conducting risk assessments for machines/equipment that use pneumatic and hydraulic energy. 1. General methods of risk assessment as indicated in standards such as ISO 12100 2. The pressure of the power source and the strength (energy) of the machine 3. Operating conditions of the equipment and machinery And more.
