Linde 0009442373 Line Break Safety Valve LB4C R-Series

Overview

The 0009442373 line break safety valve LB4C 80/1,5 is a hydraulic load-holding safety component for Linde forklifts and reach trucks. Line break valves automatically block hydraulic flow when a lift or tilt line is damaged or ruptures, helping to prevent uncontrolled lowering of the mast and load. The LB4C 80/1,5 designation identifies the valve type and its size and pressure configuration as defined by Linde.

If a technician has recommended replacing this valve, or your truck shows signs of unreliable load holding, ordering by the exact part number 0009442373 is the safest way to obtain a component that matches the original installation.

Compatibility

The 0009442373 for R-matic trucks and other Linde R-series models is used across a well-known truck family. Applications include:

• Linde R-matic
• Linde R10-R25 reach truck series
• Linde R10C

Together, these applications span the compact end of the R-series range through the higher-capacity classes. Because Linde has produced these models in many configurations over the years, we recommend confirming fitment by part number — and, where possible, by your truck’s serial number — before ordering.

Quality and Reliability

Line break valves are safety-critical components, so specification matters. This valve is supplied against the original Linde part number 0009442373, so ports, dimensions and flow characteristics are designed to match the LB4C 80/1,5 valve originally fitted to the truck. Substituting an approximate alternative for a load-holding valve can compromise holding performance, which is why we focus on exact part-number matches for Linde hydraulic and safety components.

Installation and Maintenance Tips

• Depressurize the hydraulic circuit and fully lower the forks or attachment before removing any lines.
• Keep ports, fittings and surrounding areas clean; even small amounts of contamination can affect valve seating.
• Replace seals where required and tighten fittings to the torque values given in the Linde service documentation.
• Inspect nearby hoses and hard lines while the valve is accessible, since damaged lines are a common cause of line break valve activation.
• After fitting the new 0009442373 valve, carry out a load-holding test as described in the service manual.
• Only trained technicians should carry out work on load-holding hydraulic valves.
