What type of device is required at the LPG manifold in systems with multiple cylinders?

In systems utilizing multiple LPG cylinders, having a shut-off valve or a check valve at the LPG manifold is essential for safety and functionality. The primary role of these valves is to provide a means of controlling the flow of LPG through the system. A shut-off valve allows for the complete isolation of the gas supply to the manifold, which is crucial during maintenance, repairs, or emergencies, effectively minimizing the risk of leaks or accidents.

A check valve, on the other hand, is important for preventing backflow, ensuring that gas flows in one direction only. This can prevent issues such as gas from one cylinder backing into another or even into the supply lines, which could cause malfunctions or safety risks.

While pressure regulators, flow meters, and temperature gauges are important components in LPG systems, they serve different purposes. Pressure regulators manage the pressure of the gas delivered to the appliances, flow meters measure the gas usage, and temperature gauges monitor the temperature of the system. However, without adequate shut-off or check valves, the system lacks critical safety mechanisms, making them indispensable in a manifold setup with multiple cylinders.
