Non-return valve for Demag AC 615

The non-return valve part number 69038573 serves as a hydraulic component within the bolting system of the Demag AC 615 all-terrain crane. Its primary function is to permit hydraulic fluid to flow in one direction while preventing backflow, which maintains necessary pressure within the specific circuit. This mechanism is used to control the actuators that operate the bolting system, ensuring that components remain fixed once they are positioned.

This component is compatible with the Demag AC 615 model. It is integrated into the bolting system responsible for securing segments of the boom, stabilizers, or the superstructure, which provides structural stability during crane operations. The valve is designed to facilitate a seal in the blocking direction and allow flow in the permitted direction.

Non-return valves function by using internal components such as poppets and springs to regulate hydraulic flow. By preventing reverse flow, these valves maintain the pressure required to hold hydraulic actuators in a set position, which is a standard requirement for hydraulic systems that rely on consistent pressure to support structural loads or mechanical locking mechanisms.
