Counter balance valve for Tadano TMS-1052

The counter balance valve L64175 regulates hydraulic fluid flow to control the movement of actuators such as cylinders or motors under load. By acting as a hydraulic brake, the component prevents the uncontrolled descent or acceleration of a load caused by gravity or external forces. It maintains the load in a set position and ensures smooth, precise operation during lifting or extension tasks.

This component is designed for use in Tadano and Terex machinery, including the Tadano TMS-1052, Tadano TXL300-1, Terex TMS-1052, and Terex TXL300-1 models. It is integrated into the hydraulic systems governing boom or outrigger positioning to facilitate controlled movement during heavy-duty operations.

Counter balance valves function as pressure control units that incorporate check valves and a pilot-operated relief valve. They remain closed until sufficient pilot pressure is applied, which then allows the return flow from the cylinder to release in a metered manner. This design is standard for ensuring stability in hydraulic circuits where load holding and motion control are required for safe machine operation.
