Lock valve for Terex TX760B

The lock valve, identified by part number 6111245M91, serves as a hydraulic safety component for the Terex TX760B backhoe loader. It is integrated into the hose burst protection kit for the dipper cylinder. The primary function of this valve is to prevent uncontrolled movement of the hydraulic cylinder in the event of a sudden pressure loss or hose failure. By retaining fluid within the cylinder, the valve prevents the dipper from falling or moving unexpectedly when the hydraulic supply line is compromised.

This component is specifically designed for the dipper cylinder assembly on the Terex TX760B. It ensures the stability of the load and the structural integrity of the machine during operation. By maintaining the cylinder position under load even during a pressure drop, the valve provides necessary safety during heavy-duty operations.

Lock valves are used in hydraulic systems to isolate a cylinder from the main circuit. They act as a fail-safe mechanism, holding the cylinder in a fixed position when the control valve is in neutral or when a line rupture occurs. This prevents the load from dropping, which is essential for safe operation in earthmoving and construction equipment.
