Pipe burst valve for Demag AC 615

The pipe burst valve, identified by part number 32320140, acts as a safety device within the hydraulic lift cylinder circuit of the crane. Its primary function is to monitor fluid flow and trigger an automatic shut-off if a sudden pressure drop occurs, such as from a ruptured hose or pipe. By blocking the flow, the valve secures the cylinder in place to prevent the unintended descent of the boom or load.

This component is engineered for the Demag AC 615 all-terrain crane. It integrates into the hydraulic system to maintain stability and operational control during lifting tasks. The valve operates using a flow-sensitive mechanism calibrated to respond when fluid velocity exceeds specific thresholds, ensuring that the hydraulic system remains managed even during a line failure.

Pipe burst valves are installed in hydraulic circuits to manage the flow of pressurized oil between the pump and the actuator. When a system breach causes a surge in flow, the internal mechanism shifts to restrict the passage of fluid, effectively locking the cylinder. This prevents the rapid discharge of hydraulic energy and helps maintain the position of the load until the system can be safely depressurized and repaired.
