The safety valve is fixed on the manifold to prevent system pressure from rising above the designated safety pressure. It plays a critical protective role within the system: when pressure exceeds the predetermined value, the valve opens and releases a portion of the gas, ensuring that system pressure cannot exceed the set limit. This prevents accidents caused by excessive pressure.
