In a tandem cylinder installation, it is crucial for the rupture valves to be independent to ensure safety and functionality. This design allows for each cylinder to have its own rupture valve that functions independently. If one cylinder experiences a failure or rupture, the independent rupture valve can effectively manage the situation without being influenced by the condition of the other cylinder. This redundancy is essential in maintaining system integrity and safety, especially in scenarios that may involve high-pressure operations. The independence ensures that if one valve fails, it does not compromise the operation of the other cylinder's valve, thus minimizing the risk of catastrophic failure.

The possibility of interconnected valves, sharing a valve, or relying on a single valve for both cylinders could lead to complications where a failure in one area could affect the other, potentially jeopardizing safety and operational reliability. Therefore, having independent rupture valves is a sound engineering practice that emphasizes safety in hydraulic systems involving tandem cylinders.
