Locking valve for Terex TX760B

The 6109882M91 locking valve serves as a safety component within the hydraulic system of the Terex TX760B backhoe loader. Often referred to as a hose burst valve for the dipper, this component is integrated into the hose burst kit for the quick attach boom cylinder. Its primary function is to detect a sudden loss of pressure resulting from a ruptured hydraulic hose and to immediately restrict fluid flow. By locking the hydraulic fluid within the cylinder, the valve prevents the unintended collapse or movement of the boom or attached equipment, thereby maintaining stability during a hydraulic failure.

This component is compatible with the Terex TX760B model. It is designed to function within the specific hydraulic circuit of the boom assembly to ensure operator safety and protect the machine from damage during operation. The valve provides a rapid response to pressure drops, which is necessary for equipment handling heavy loads in dynamic environments.

Locking valves or hose burst valves are standard safety features in heavy machinery hydraulic systems. They are typically installed directly at the cylinder port to ensure that if a supply line fails, the load remains supported by the trapped fluid until the system can be safely depressurized or repaired.
